what element of an essay restates the main idea

Understanding & Interacting with a Text

Finding the main idea in a piece of writing is a basic reading skill. No matter what type of expository text you read, the primary comprehension goal is to identify the main idea: the most important point that the writer wants to communicate.  Main ideas are often stated toward the start of a text, usually in an introductory paragraph. They are often repeated in fuller form toward the end of a text, usually in a concluding paragraph. Main ideas may be reinforced through headings, subheadings, and other forms of emphasis. However, main ideas may also be implied and not stated directly in the text.  Sometimes you need to infer the main idea based on the details, facts, and explanations in the text.

Some texts make the task of identifying the main idea relatively easy. Articles in scholarly journals often include an abstract, which is a condensed version of the information in the article, a version which focuses on main ideas. Textbooks, articles in general interest magazines, and online articles in blogs or on websites may include headings and subheadings which make it easier to identify core concepts. All types of texts may include graphic features such as sidebars, diagrams, and charts, which help readers understand complex information and distinguish between essential and inessential points. When reading a text with these features, use them to help identify the main idea.

For texts without graphic features, headings, or abstracts, and/or for texts with implied main ideas, use the following process to identify the main idea:

• Read the text.
• Ask yourself: What is the text about? – What is the topic?
• Ask yourself: What is the author saying about the topic?
• Identify repeated concepts and language; writers often use repetition to emphasize a main idea.
• Summarize the article after you read–put what you think the main idea is into your own words.  See if you can find any statements in the article that are similar to your summary.  If so, it’s likely that you’ve found the main idea.  If the main idea in the text is not stated but implied, then ask if your summary encapsulates the one thing you think the writer wants you to understand about the topic.

For a discussion of finding the main idea which includes examples, link to Finding the Main Idea from Monterey Peninsula College’s Writing Center.

The following two videos also provide very clear, useful discussions of finding the main idea in a text.

Read the article, “ Wikipedia Is Good for You!? ”  Then choose the statement that you think best offers the main idea.  In the answer, you’ll also find one reader’s discussion of her thought process finding the main idea.

• Wikipedia is a good source in certain cases.
• Wikipedia, although itself not always a valid source, is useful as a starting place for ideas, search terms, and other sources.
• Wikipedia, although itself not always a valid source, is useful both as a starting place and as a process guide to producing a text.

The third choice best offers the article’s main idea. I knew that the main idea would have something to do with the topic “Wikipedia,” because of the title.  But because the title included a question mark, I didn’t know if the main idea would end up being for or against Wikipedia.  Immediately after I skimmed, I thought that the main idea was stated directly in paragraph 12: “ There are productive ways to use Wikipedia. In fact, Wikipedia can be a good source in three different ways. Rather than a source to cite, it can be a source of (1) ideas, (2) links to other texts, and (3) search terms. ”  But when I read more fully, I realized that there were other things the author wanted me to understand, concepts more complex and nuanced than a direct “yes” or “no” answer to the title.  I found key ideas relating to the benefits of Wikipedia in paragraphs 2 and 4 in addition to 12. Paragraphs 2 and 4 discussed Wikipedia in terms of writing processes: the need to go back and revise, the co-production of an article’s text based on input from many sources (a “conversation”), and the concept of writing for a real audience. There are also a number of paragraphs that talk about the detriments of Wikipedia if used as a source.  Since there’s no single main idea sentence, I summarized the main concepts into a sentence that condensed and synthesized the article’s ideas into one main idea statement.

Essay Organization – Overview

There are various types of writing assignments an instructor may give such as journals, reaction papers, questions to be answered, paragraphs on topics or questions, essays, and research papers.

An  essay  is a writing on a specific question or topic.  Instructors may vary in what they are expecting when they assign an  essay .  It’s important to always ask your instructor if you are not sure.  Some may simply want a discussion on a topic or question and are not asking for formal organization.

Others may be expecting a formal academic essay, also called a thesis-and-support paper, organized with an introduction, body, and conclusion that includes the following parts:

an introductory paragraph which gives a background and states the thesis (the point of the essay

a concluding paragraph which sums up the proof and restates the thesis.

body paragraphs which contain proof, also called supporting ideas, of the thesis statement

While some instructors may have slight variations about formal academic essay organization, you won’t have a problem if your paper has the following three components:

a thesis statement at the end of the introductory (opening) paragraph

body paragraphs contain only proof of the thesis, and

a concluding paragraph which contains a review of the proof and restatement of the thesis.  Some instructors also ask for some general prediction or observation instead of or in addition to a restatement of thesis.

Always check with your instructor if you are not sure about what is expected.  The discussion here is for a formal academic essay (thesis-and-support paper).

What is an academic essay and how should it look?

An essay is a collection of paragraphs that fit around one idea or position on an issue. This is usually called the  thesis  or  main idea .

The sentence that contains the main idea is called the Thesis Statement.  The Thesis Statement must take a position and not just state a fact.   While some instructors vary on where a thesis statement may appear, it is safe to place it as th last sentence of the first paragraph.

An academic essay must have at least three paragraphs: an introduction, a body paragraph, and a concluding paragraph.  Since there should be a separate body paragraph for each proof point, the more substantial the proof, the more paragraphs there will be. A typical essay of about five hundred words will usually have at least two or three proof paragraphs making the essay four to five paragraphs.

Instructors often require a specific page format (margins, line spacing, and so on).  Page formatting is part of the requirements of a style system.  Both MLA and APA styles have similar formatting requirements.  Unless your instructor states otherwise, it use MLA page format.

In a way, these academic essays are like a court trial.  The attorney, whether prosecuting the case or defending it, begins with an opening statement explaining the background and telling the jury what he or she intends to prove (the thesis statement).  Then, the attorney presents witnesses for proof (the body of the paragraphs).  Lastly, the attorney presents the closing argument (concluding paragraph).

The Introduction and Thesis

There are a variety of approaches regarding the content of the introduction paragraph such as a brief outline of the proof, an anecdote, explaining key ideas, and asking a question.  In addition, some textbooks say that an introduction can be more than one paragraph.  The placement of the thesis statement is another variable depending on the instructor and/or text.  The approach used in this lesson is that an introduction paragraph gives background information leading into the thesis which is the main idea of the paper, which is stated at the end.

The background in the introductory paragraph consists of information about the circumstances of the thesis. This background information often starts in the introductory paragraph with a general statement which is then refined to the most specific sentence of the essay, the thesis. It is important to note that in this approach, the proof for the thesis is not found in the introduction except, possibly, as part of a thesis statement which includes the key elements of the proof. Proof is presented and expanded on in the body.

The thesis is the position statement. It must contain a subject and a verb and express a complete thought. It must also be defensible. This means it should be an arguable point with which people could reasonably disagree. The more focused and narrow the thesis statement, the better a paper will generally be.

If you are given a question in the instructions for your paper, the thesis statement is a one-sentence answer taking a position on the question.

If you are given a topic instead of a question, then in order to create a thesis statement, you must narrow your analysis of the topic to a specific controversial issue about the topic to take a stand. If it is not a research paper, some brainstorming (jotting down what comes to mind on the issue) should help determine a specific question.

If it is a research paper, the process begins with exploratory research which should show the various issues and controversies which should lead to the specific question.  Then, the research becomes focused on the question which in turn should lead to taking a position on the question.

These methods of determining a thesis are still answering a question. It’s just that you pose a question to answer for the thesis.  Here is an example.

Suppose, one of the topics you are given to write about is America’s National Parks. Books have been written about this subject. In fact, books have been written just about a single park. As you are thinking about it, you may realize how there is an issue about balancing between preserving the wilderness and allowing visitors. The question would then be Should visitors to America’s National Parks be regulated in order to preserve the wilderness?

One thesis might be There is no need for regulations for visiting America’s National Parks to preserve the wilderness.

 Another might be There should be reasonable regulations for visiting America’s National Parks in order to preserve the wilderness.

Finally, avoid using expressions that announce, “Now I will prove…” or “This essay is about …” Instead of telling the reader what the paper is about, a good paper simply proves the thesis in the body. Generally, you shouldn’t refer to your paper in your paper.

Here is an example of a good introduction with the thesis in red:

Not too long ago, everyday life was filled with burdensome, time-consuming chores that left little time for much more than completing these tasks.  People generally worked from their homes or within walking distance to their homes and rarely traveled far from them.  People were limited to whatever their physical capacities were.  All this changed dramatically as new technologies developed.  Modern technology has most improved our lives through convenience, efficiency, and accessibility.

Note how the background is general and leads up to the thesis.   No proof is given in the background sentences about how technology has improved lives.

Moreover, notice that the thesis in red is the last sentence of the introduction. It is a defensible statement.

A reasonable person could argue the opposite position:  Although modern technology has provided easier ways of completing some tasks, it has diminished the quality of life since people have to work too many hours to acquire these gadgets, have developed health problems as a result of excess use, and have lost focus on what is really valuable in life.

Quick Tips:

The introduction opens the essay and gives background information about the thesis.

Do not introduce your supporting points  (proof) in the introduction unless they are part of the thesis; save these for the body.

The thesis is placed at the end of the introductory paragraph.

Don’t use expressions like “this paper will be about” or “I intend to show…”

For more information on body paragraphs and supporting evidence, see Proving a Thesis – Evidence and Proving a Thesis – Logic, and Logical Fallacies and Appeals in Related Pages on the right sidebar.

Body paragraphs give proof for the thesis.  They should have one proof point per paragraph expressed in a topic sentence. The topic sentence is usually found at the beginning of each body paragraph and, like a thesis, must be a complete sentence. Each topic sentence must be directly related to and support the argument made by the thesis.

After the topic sentence, the rest of the paragraph should go on to support this one proof with examples and explanation. It is the details that support the topic sentences in the body paragraphs that make the arguments strong.  Proof may include discussion of an opposing view, but it must include a rebuttal explaining why that opposing view does not make sense or otherwise not be considered valid.

If the thesis statement stated that technology improved the quality of life, each body paragraph should begin with a reason why it has improved the quality of life.  This reason is called a  topic sentence .  Following are three examples of body paragraphs that provide support for the thesis that modern technology has improved our lives through convenience, efficiency, and accessibility:

     Almost every aspect of our lives has been improved through convenience provided by modern technology.  From the sound of music from an alarm clock in the morning to the end of the day being entertained in the convenience of our living room, our lives are improved.  The automatic coffee maker has the coffee ready at a certain time.  Cars or public transportation bring people to work where computers operate at the push of a button.  At home, there’s the convenience of washing machines and dryers, dishwashers, air conditioners, and power lawn mowers.  Some may say the conveniences are not worth the extra cost and effort keeping these devices working, but, overwhelmingly, people opt to use them.  Modern technology has made life better with many conveniences.

     Not only has technology improved our lives through convenience, it has improved our lives through efficiency. The time saved by machines doing most of the work leaves more time for people to develop their personal goals or to just relax.  Years ago, when doing laundry could take all day, there wasn’t time left over to read or go to school or even just to take a leisurely walk.  The opposing view might argue that people misuse their increased free time sitting around and watching television.  While some people have health problems as a result of technology, by far, lives are improved. Nowadays, people have more time and energy than ever to simply enjoy their lives and pursue their goals thanks to the efficiency of modern technology.

     Accessibility to a wide range of options has been expanded through modern technology.  Never before could people cross a continent or an ocean in an afternoon.  Travel is not the only way technology has created accessibility.  Software which types from voice commands has made using computers more accessible for school or work.  People with special needs have many new options thanks to modern technology such as special chairs or text readers.  Actually, those people who need hearing aids as a result of normal aging have access to continued communication and enjoyment of entertainment they did not previously have. There are many ways technology has improved lives through increased accessibility.

Notice how these proof paragraphs stick to one proof point introduced in the topic sentences in red. These three paragraphs, not only support the original thesis, but go on to give details and explanations which explain the proof point in the topic sentence.

Some instructors would like a rebuttal paragraph which raises the opposing arguments and explains why they are not valid instead of addressing opposition within the paragraphs as appropriate as shown in the above essay.  In that case, the rebuttal should go before the conclusion.

Quick Tips on Body Paragraphs

• The body of your essay is where you give your main support for the thesis.
• Each body paragraph should start with a Topic Sentence that is directly related to and supports the thesis statement.
• Each body paragraph should also give details and explanations that further support the poof point for that paragraph.
• Don’t use enumeration such as first, second, and third. The reader will know by the topic sentence that it is a new proof point.

See Proving the Thesis in Related Pages on the right sidebar for more information on proof.

The Conclusion

Instructors vary of what they expect in the conclusion; however, there is general agreement that conclusions should not introduce any new proof points, should include a restatement of the thesis, and should not contain any words such as “In conclusion.”

Some instructors want only a summary of the proof and a restatement of the thesis. Some instructors ask for a general prediction or implication of the information presented without a restatement of thesis. Still others may want to include a restatement along with a general prediction or implication of the information presents. Be sure to review assignment instructions or check with instructor.  If your assignment instructions don’t specify, just sum up the proof and restate the thesis.

Example which sums up proof and restates thesis :

Modern technology has created many conveniences in everyday from waking up to music to having coffee ready to getting to work and doing a day’s work.  The efficiency provided by technology gives people more time to enjoy life and pursue personal development, and the accessibility has broadened options for travel, school, and work.  Modern technology has improved our lives through convenience, efficiency, and accessibility.

See how the thesis statement was restated in red. The two major arguments about the possible locations proven to be incorrect were also included to remind the reader of the major proof points made in the paper.

Example which makes a general prediction or implication of the information presented:

Modern technology has created many conveniences in everyday life from waking up to music to having coffee ready to getting to work and doing a day’s work.  The efficiency provided by technology gives people more time to enjoy life and pursue personal development, and the accessibility has broadened options for travel, school, and work.  Without it, everyday life would be filled with burdensome tasks and be limited to our neighborhood and our physical capacity. Here’s an example of a conclusion with a general prediction or implication statement with a restatement of thesis.

Modern technology has created many conveniences in everyday life from waking up to music to having coffee ready to getting to work and doing a day’s work.  The efficiency provided by technology gives people more time to enjoy life and pursue personal development, and the accessibility has broadened options for travel, school, and work.  Without it, everyday life would be filled with burdensome tasks and be limited to our neighborhood and our physical capacity. Modern technology has improved our lives through convenience, efficiency, and accessibility.

Quick Tips for Conclusions

• The conclusion brings the essay to an end and is typically the shortest paragraph.
• It is important to not introduce new ideas or information here.
• Unless otherwise specified in your assignment, just sum up the proof and restate the conclusion.
• Some instructors may want the concluding paragraph to contain a general prediction or observation implied from the information presented.

Rhetoric is the art of persuasion.  Rhetorical modes are ways of using language with a specific focus.   Narration,  for example, tells a story or a sequence of events.  A narrative essay tells a story.

Other rhetorical modes focus on describing, defining, using examples (exemplification), or classifying as the primary purpose.  Comparing and contrasting simply compares one thing to another showing the differences as well as the similarities.

In a cause and/or effect paper, the causes and/or effects of a situation are the focus.

A persuasive or argumentative paper proves a position on a controversial issue.

Sometimes, instructors assign essays requiring a specific mode such as defining something or discussing the causes of a problem. These are considered useful ways to develop the particular skill such as looking closely at something to describe it or finding ways to define an object or situation.

More commonly, however, a writing assignment does not require a specific mode;  these strategies are used as appropriate within an essay or other writing.  For example, a paper arguing that pesticides are harmful might include information  defining  and  describing  various pesticides. It could include  classifying  them by potential harm and use  examples  of the types of pesticides.  It could have information on the  effects  of particular pesticides.

It can be argued that all papers, regardless of the primary rhetorical strategy used, are persuasive or argumentative since all writing ultimately is to prove something – even if it is only the legitimacy of one’s feelings such as in a reaction paper or creative writing.  Most writing blend the uses of rhetorical styles.

Unity and Coherence

Like all effective writing, essays must have unity.  They must clearly stay focused on one purpose: proving the thesis.  All the sentences in each paragraph and each paragraph must work together to achieve that purpose.  It is critical for each sentence in each paragraph to start with a topic sentence that states a reason why the thesis is right and that the rest of the sentences in the paragraph support that topic sentence.

Essays must have coherence.  Each sentence must flow smoothly and logically into the next.  Each paragraph must flow smoothly and logically into the next.  Words and word groups called  transitions  must be used to link one sentence to the next and one paragraph to the next.

See Unity and Coherence in Essays in Related Pages on the right side bar for more information.

Word Use (Appropriate Language)

Generally speaking, use of Standard English vocabulary and grammar is expected.  These types of papers should not sound as though you were talking casually to a friend.  Don’t use slang, for example, such as  ok.   Also, while we use second person (you, your) in informal speech, formal academic writing should not use second person since the reference is not specific.  Here’s an example.  You should know where your children are.   The reader may not have young children or any children at all.  Here’s an example with clear reference.   Parents of young children should know where their children are.

Instructors will vary about accepting the use of first person (I, me, my, we, us, our) in essay writing.  While first person may be appropriate in journal writing or reaction papers, typically, instructors will require third person (not first or second) in formal essays and research essays. Be aware of requirements for any particular assignment.

Formal academic essays should not include sentences that refer to yourself or the paper.  Don’t use statements such as “In the opinion of this writer (referring to yourself)….” or “This paper will show….”

For more information on language use, see Appropriate Language in Related Pages on the right sidebar. 

Literary Analysis Essay - Close Reading

The purpose of a literary analysis essay is to carefully examine and sometimes evaluate a work of literature or an aspect of a work of literature. Examining the different elements of a pieces of literature including plot, character, setting, point of view, irony, symbolism, and style to see how the author develops theme is not an end in itself but rather a process to help you better appreciate and understand the work of literature as a whole. The focus of a literary analysis essay is as expansive as the writers’ interests. For example, a short story analysis might include identifying a particular theme and then showing how the writer suggests that theme through the point of view of the story. It is important to remember that literary analysis does not merely demonstrate a particularly literary element. The focus is explaining how that element is meaningful or significant to the work as a whole. See Essay Organization and Elements of Fiction for more information.

Close reading is deep analysis of how a literary text function; it is both a reading process and something you include in a literary analysis paper. When you read a text paying specific attention to certain literary elements, looking for particular patters, or following the development of a particular character, you are practicing close reading. Likewise, when you watch a film with particular emphasis on a certain element, you are doing a close reading. Of course, when one writes an essay that teases out a certain element, this is the beginning of a close reading. Like literary analysis more generally, close reading is not a means in and of itself. Close reading helps inform the larger meaning or import of a work.

Literary analysis involves examining the components of a literary text, which allows us to focus on small parts of the text, clues to help us understand the work as a whole. The process of close reading should produce questions. When you begin to answer these questions, you are ready to participate thoughtfully in class discussion or write a literary analysis paper. Close reading is a process of finding as much information as you can in order form to as many questions as you can.

An outline includes the thesis and proof points.  It is the skeleton of an academic essay.  Starting with an outline can be extremely helpful in writing an essay.  Once an outline is completed, it is a matter of developing the proof points (body paragraphs),adding a background before the thesis for an introduction paragraph, and adding a concluding paragraph.  See Outlining in Related Pages on the right sidebar for more information.

The important thing in essay writing is to have a point, thereby knowing what you are trying to prove, and stick to that point.  Keep it simple and focused.

This format is the basis for writing a research paper as well.  If you can get the idea in a simple essay, writing research papers will be much easier.

Writing a Paper: Conclusions

Writing a conclusion.

A conclusion is an important part of the paper; it provides closure for the reader while reminding the reader of the contents and importance of the paper. It accomplishes this by stepping back from the specifics in order to view the bigger picture of the document. In other words, it is reminding the reader of the main argument. For most course papers, it is usually one paragraph that simply and succinctly restates the main ideas and arguments, pulling everything together to help clarify the thesis of the paper. A conclusion does not introduce new ideas; instead, it should clarify the intent and importance of the paper. It can also suggest possible future research on the topic.

An Easy Checklist for Writing a Conclusion

It is important to remind the reader of the thesis of the paper so he is reminded of the argument and solutions you proposed.

Think of the main points as puzzle pieces, and the conclusion is where they all fit together to create a bigger picture. The reader should walk away with the bigger picture in mind.

Make sure that the paper places its findings in the context of real social change.

Make sure the reader has a distinct sense that the paper has come to an end. It is important to not leave the reader hanging. (You don’t want her to have flip-the-page syndrome, where the reader turns the page, expecting the paper to continue. The paper should naturally come to an end.)

No new ideas should be introduced in the conclusion. It is simply a review of the material that is already present in the paper. The only new idea would be the suggesting of a direction for future research.

Conclusion Example

As addressed in my analysis of recent research, the advantages of a later starting time for high school students significantly outweigh the disadvantages. A later starting time would allow teens more time to sleep--something that is important for their physical and mental health--and ultimately improve their academic performance and behavior. The added transportation costs that result from this change can be absorbed through energy savings. The beneficial effects on the students’ academic performance and behavior validate this decision, but its effect on student motivation is still unknown. I would encourage an in-depth look at the reactions of students to such a change. This sort of study would help determine the actual effects of a later start time on the time management and sleep habits of students.

Parts of an Essay?

Components of an Essay

An essay is a piece of writing that is written to provide information about a certain topic or simply to convince the reader. In every effective essay writing , there are three major parts: introduction , body , and essay conclusion .

• The introduction.  This is where the subject or topic is introduced. The big picture, points, and ideas are briefly written here.
• The body.  All the main ideas, topics, and subject are discussed here in details. This also includes evidence or information that support the essay.
• The conclusion.  The last part of an essay and usually summarizes the overall topic or ideas of an essay.

How to Write the Introduction Essay?

The introduction is the door to the whole essay outline . It must be convincing enough to get the attention of the readers. The following are the guidelines for writing the introduction of the essay.

• It must contain an attention-getter sentence or statement.
• The introduction must sound interesting to capture the attention of the reader.
• You can quote a statement about a topic or something related to the whole point of your essay.
• The intro must move from general to specific.
• At the end, there must be a thesis statement that gives an insight to the author’s evidence.

What Does the Body of an Essay Contain?

The body is the longest part of the essay and commonly highlights all the topics and ideas. The body must include the following:

• The evidence and supporting details of the expository essay in addition to the author’s ideas.
• A topic or sentences that link the discussion back to the thesis statement.
• The logical ordering of the ideas. The chronological of time, ideas, and evidence.
• A set of transition statements or sentences to create a good flow of the essay.
• Sufficient examples, evidence, data, and information that must be relevant to the particular topic of the essay.

The Conclusion of the Essay

The conclusion is the last part of the essay, and should:

• Emphasize on the major takeaways of the essay.
• Wrap up and summarize the essay, as well as the arguments, ideas, and points.
• Restate the main arguments in a simplified and clear manner that must be understood by the reader.
• Guarantee that the reader is left with something to think about, especially the main point of your essay.

The Elements of an Essay

• Thesis statement.  It is the main proposition of an essay. The thesis statement must be arguable that differentiates it from a fact and must be in a persuasive writing style.
• Problem or question.  The problem statements or the important issue of the essay that must be defined and described in the essay.
• Motive.  The reason for writing the essay.
• Evidence.  The facts and data or information that supports the whole essay and prove the main point of the essay.
• Analysis & reflection.  In which the writer turns the evidence into an arguable statement that provides the reader how the evidence supports, develops, or explained the essay’s thesis statement.
• Structure.  The work that the writer does to organize the idea, the series of sub-topics and sections through which it is explained and developed.

Elements of an Essay

Definition of elements of an essay.

An essay is a piece of composition that discusses a thing, a person, a problem, or an issue in a way that the writer demonstrates his knowledge by offering a new perspective , a new opinion, a solution, or new suggestions or recommendations. An essay is not just a haphazard piece of writing. It is a well-organized composition comprising several elements that work to build an argument , describe a situation, narrate an event, or state a problem with a solution. There are several types of essays based on the purpose and the target audience . Structurally, as an essay is an organized composition, it has the following elements:

• Introduction
• Body Paragraphs

Nature of Elements of an Essay

An essay has three basic elements as given above. Each of these elements plays its respective role to persuade the audience, convince the readers, and convey the meanings an author intends to convey. For example, an introduction is intended to introduce the topic of the essay. First it hooks the readers through the ‘ hook ,’ which is an anecdote , a good quote, a verse , or an event relevant to the topic. It intends to attract the attention of readers.

Following the hood, the author gives background information about the topic, which is intended to educate readers about the topic. The final element of the introduction is a thesis statement. This is a concise and compact sentence or two, which introduces evidence to be discussed in the body paragraphs.

Body paragraphs of an essay discuss the evidences and arguments introduced in the thesis statement . If a thesis statement has presented three evidences or arguments about the topic, there will be three body paragraphs. However, if there are more arguments or evidences, there could be more paragraphs.

The structure of each body paragraph is the same. It starts with a topic sentence, followed by further explanation, examples, evidences, and supporting details. If it is a simple non-research essay, then there are mostly examples of what is introduced in the topic sentences. However, if the essay is research-based, there will be supporting details such as statistics, quotes, charts, and explanations.

The conclusion is the last part of an essay. It is also the crucial part that sums up the argument, or concludes the description, narration, or event. It is comprised of three major parts. The first part is a rephrasing of the thesis statement given at the end of the introduction. It reminds the readers what they have read about. The second part is the summary of the major points discussed in the body paragraphs, and the third part is closing remarks, which are suggestions, recommendations, a call to action, or the author’s own opinion of the issue.

Function of Elements of an Essay

Each element of an essay has a specific function. An introduction not only introduces the topic, but also gives background information, in addition to hooking the readers to read the whole essay. Its first sentence, which is also called a hook, literally hooks readers. When readers have gone through the introduction, it is supposed that they have full information about what they are going to read.

In the same way, the function of body paragraphs is to give more information and convince the readers about the topic. It could be persuasion , explanation, or clarification as required. Mostly, writers use ethos , pathos , and logos in this part of an essay. As traditionally, it has three body paragraphs, writers use each of the rhetorical devices in each paragraph, but it is not a hard and fast rule. The number of body paragraphs could be increased, according to the demand of the topic, or demand of the course.

As far as the conclusion is concerned, its major function is to sum up the argument, issue, or explanation. It makes readers feel that now they are going to finish their reading. It provides them sufficient information about the topic. It gives them a new perspective, a new sight, a new vision, or motivates them to take action. The  conclusion needs to also satisfy readers that they have read something about some topic, have got something to tell others, and that they have not merely read it for the sake of reading.

Analyze Thesis or Main Ideas of Texts

Being able to identify the purpose and thesis of a text, while you’re reading it, takes practice. Questioning the text you’re reading is a good place to start. When trying to isolate the thesis, or main idea, of your reading material, consider these questions:

• What is the primary subject of this text?
• Is the author trying to inform me, or persuade me?
• What does the author think I need to know about this subject?
• Why does the author think I need to know about this subject?

Sometimes the answer to these questions will be very clearly stated in the text itself. Sometimes it is less obvious, and in those cases, the techniques on the following page will be useful.

Implicit vs. Explicit Main Idea/ Thesis Statements

According to author Pavel Zemliansky,

Arguments then, can be explicit and implicit, or implied. Explicit arguments contain noticeable and definable thesis statements and lots of specific proofs. Implicit arguments, on the other hand, work by weaving together facts and narratives, logic and emotion, personal experiences and statistics. Unlike explicit arguments, implicit ones do not have a one-sentence thesis statement. Instead, authors of implicit arguments use evidence of many different kinds in effective and creative ways to build and convey their point of view to their audience. Research is essential for creative effective arguments of both kinds.

Even if what you’re reading is an informative text, rather than an argumentative one, it might still rely on an implicit thesis statement. It might ask you to piece together the overall purpose of the text based on a series of content along the way.

The following video defines the key terms explicit and implicit, as they relate to thesis statements and other ideas present in what you read. It also introduces the excellent idea of the reading voice and the thinking voice that strong readers use as they work through a text.

To help keep you on your toes, the author of this video challenges you to find her spelling mistake in one of her cards along the way!

Thesis and Topic Sentences

You’ll remember that the first step of the reading process, previewing, allows you to get a big-picture view of the document you’re reading. This way, you can begin to understand the structure of the overall text. A later step in the reading process, summarizing , allows you to encapsulate what a paragraph, section, or the whole document is about. When summarizing individual paragraphs, it’s likely that your summary ends up looking like a paraphrase of that paragraph’s topic sentence .

A paragraph is composed of multiple sentences focused on a single, clearly-defined topic. There should be exactly one main idea per paragraph, so whenever an author moves on to a new idea, he or she will start a new paragraph. For example, this paragraph defines what a paragraph is, and now we will start a new paragraph to deal with a new idea: how a paragraph is structured.

Paragraphs are actually organized much like persuasive papers are. Just like a paper has a thesis statement followed by a body of supportive evidence, paragraphs have a topic sentence followed by several sentences of support or explanation. If you look at this paragraph, for example, you will see that it starts with a clear topic sentence letting you know that paragraphs follow a structure similar to that of papers. The next sentence explains how a paragraph is like a paper, and then two more sentences show how this paragraph follows that structure. All of these sentences are clearly connected to the main idea.

The topic sentence of a paragraph serves two purposes: first, it lets readers know what the paragraph is going to be about; second, it highlights the connection between the present paragraph and the one that came before. The topic sentence of this paragraph explains to a reader what a topic sentence does, fulfilling the first function. It also tells you that this paragraph is going to talk about one particular aspect of the previous paragraph’s main idea: we are now moving from the general structure of the paragraph to the particular role of the topic sentence.

After the topic sentence introduces the main idea, the remainder of the sentences in a paragraph should support or explain this topic. These additional sentences might detail the author’s position on the topic. They might also provide examples, statistics, or other evidence to support that position. At the end of the paragraph, the author may include some sort of conclusion or a transition that sets up the next idea he or she will be discussing (for example, you can see this clearly in the last sentence of the third paragraph).

The Three Parts of a Paragraph

The topic is the subject of the paragraph. It can be:

• A few words long
• These words (or words related to the topic) are typically repeated throughout the paragraph
• Answers the question: What is this paragraph about?

2) Main Idea

This is the writer’s overall point. It can be:

• If stated in the paragraph, it’s called a “topic sentence”
• If unstated in the paragraph, the reader must figure it out (infer it) from details
• General enough to cover the more specific supporting details
• Usually (but not always!) near the beginning of the paragraph
• Answers the question: What is the overall point being made about the topic?”

3) Supporting Details

These are the details in the paragraph that support the main idea. They can be either major or minor supporting details.

Tips for Identifying Main Ideas

Although you are learning to put the main idea first in your own paragraphs, professional writers often don’t. Sometimes the first sentence of a paragraph provides background information, poses a question, or serves as a bridge from a previous paragraph. Don’t assume it is the main idea. Use these tips instead:

• Look for a general statement that appears to “cover” the other information.
• Figure out the general topic of the paragraph first. Then ask yourself, “What point is the writer trying to make about this topic?”
• Look for clue words. Main ideas sometimes have words such as “some” or plural nouns like “ways” or “differences” that signal a list of details to come.
• Is this statement supported by most of the other information?
• If I turn this statement into a question, does the other information answer it?

SPECIAL NOTE: Sometimes a main idea covers more than one paragraph. This may happen in newspaper articles or when the writer has a lot to say about one topic.

Difference Between the Topic and Main Idea

To understand the difference between a main idea and the topic, imagine that you are listening to your friends talk about their pets. The TV is on, so all you can make out are the name of their pets. If someone asked you what the topic was, you would say “pets.” But because you couldn’t hear the whole thing, you didn’t understand the “main idea” was whose pet was the best. The topic is very broad – the main idea is more specific. The sentences that follow in the paragraph exercise offer examples or descriptions to illustrate or explain the main idea. Note the reading-writing connection--while we are finding the main idea as readers, we will be using the main ideas to write topic sentences in paragraphs.

Exercise \(\PageIndex{1}\)

Read the following paragraph and then decide what the main idea is.

One myth about exercise is that if a woman lifts weights, she will develop muscles as large as a man’s. Without male hormones, however, a woman cannot increase her muscle bulk as much as a man’s. Another misconception about exercise is that it increases the appetite. Actually, regular exercise stabilizes the blood-sugar level and prevents hunger pangs. Some people also think that a few minutes of exercise a day or one session a week is enough, but at least three solid workouts a week are needed for muscular and cardiovascular fitness.

Choose the Main Idea:

a) Women who lift weights cannot become as muscular as men.

b) There are several myths about exercise.

c) Exercise is beneficial to everyone.

d) People use many different excuses to avoid exercising.

Explain why you did or did not choose each possible answer above.

a) ________________________________________________________________________

________________________________________________________________________

b) ________________________________________________________________________

c) ________________________________________________________________________

d) ________________________________________________________________________

Exercise \(\PageIndex{2}\)

“To Sherlock Holmes she is always THE woman. I have seldom heard him mention her under any other name. In his eyes she eclipses and predominates the whole of her sex. It was not that he felt any emotion akin to love for Irene Adler. All emotions, and that one particularly, were abhorrent to his cold, precise but admirably balanced mind. He was, I take it, the most perfect reasoning and observing machine that the world has seen, but as a lover he would have placed himself in a false position. He never spoke of the softer passions, save with a gibe and a sneer. They were admirable things for the observer--excellent for drawing the veil from men's motives and actions. But for the trained reasoner to admit such intrusions into his own delicate and finely adjusted temperament was to introduce a distracting factor which might throw a doubt upon all his mental results.“

The main idea of this paragraph is the first sentence. The first sentence identifies the two characters that the rest of the paragraph is going to describe, and suggests at their relationship. Each sentence that follows either describes the woman, Sherlock Holmes, or how he felt about her or her effect on him.

Exercise \(\PageIndex{3}\)

Here is another example from the same story, see if you can find the main idea:

One night--it was on the twentieth of March, 1888--I was returning from a journey to a patient (for I had now returned to civil practice), when my way led me through Baker Street. As I passed the well-remembered door, which must always be associated in my mind with my wooing, and with the dark incidents of the Study in Scarlet, I was seized with a keen desire to see Holmes again, and to know how he was employing his extraordinary powers. His rooms were brilliantly lit, and, even as I looked up, I saw his tall, spare figure pass twice in a dark silhouette against the blind. He was pacing the room swiftly, eagerly, with his head sunk upon his chest and his hands clasped behind him. To me, who knew his every mood and habit, his attitude and manner told their own story. He was at work again.

a. One night--it was on the twentieth of March, 1888--I was returning from a journey to a patient (for I had now returned to civil practice), when my way led me through Baker Street.

b. As I passed the well-remembered door, which must always be associated in my mind with my wooing, and with the dark incidents of the Study in Scarlet, I was seized with a keen desire to see Holmes again, and to know how he was employing his extraordinary powers

c. His rooms were brilliantly lit, and, even as I looked up, I saw his tall, spare figure pass twice in a dark silhouette against the blind.

d. He was pacing the room swiftly, eagerly, with his head sunk upon his chest and his hands clasped behind him.

The correct answer is a. The first sentence gives you the point-of-view, or who is the person explaining what is happening, and it lets you know that this person is going into a particular place. Each of the other sentences describes the place where he, Dr. Watson, entered, what it looked like, and who was in there.

B is not as strong a choice as a, because it refers to Study in Scarlet and Holmes’ powers, which are not described in the rest of the paragraph. Choice B is too specific to be the main idea of this paragraph. Choices c and d are not correct because they are describing Holmes’ actions, and his walking is not what the whole paragraph is about.

Exercise \(\PageIndex{4}\)

Let’s try one more. Read the following and select which one is the main idea from the list below:

“At three o'clock precisely I was at Baker Street, but Holmes had not yet returned. The landlady informed me that he had left the house shortly after eight o'clock in the morning. I sat down beside the fire, however, with the intention of awaiting him, however long he might be. I was already deeply interested in his inquiry, for, though it was surrounded by none of the grim and strange features which were associated with the two crimes which I have already recorded, still, the nature of the case and the exalted station of his client gave it a character of its own. Indeed, apart from the nature of the investigation which my friend had on hand, there was something in his masterly grasp of a situation, and his keen, incisive reasoning, which made it a pleasure to me to study his system of work, and to follow the quick, subtle methods by which he disentangled the most inextricable mysteries. So accustomed was I to his invariable success that the very possibility of his failing had ceased to enter into my head.”

a. At three o'clock precisely I was at Baker Street, but Holmes had not yet returned.

b. The landlady informed me that he had left the house shortly after eight o'clock in the morning.

c. I sat down beside the fire, however, with the intention of awaiting him, however long he might be

d. I was already deeply interested in his inquiry, for, though it was surrounded by none of the grim and strange features which were associated with the two crimes which I have already recorded, still, the nature of the case and the exalted station of his client gave it a character of its own.

The way to figure out that the answer, this time, is d, is to look at each sentence that follows and ask, does this refer back to the location, Baker Street? Do they refer back to the landlady? Do they refer back to Dr. Watson’s waiting? Or, do they refer back to the case? They both refer back to the current investigation, by talking about Holmes’ way of untangling mysteries, and that Watson’s belief that the investigation would be a success.

The introduction to this paragraph may have thrown you off so be careful to read through the entire paragraph each time, and look at each sentence and its role within the paragraph. Mostly the main idea comes right up front – but not always!

Reading-Writing Connection: Thesis Statements

Exercise \(\PageIndex{5}\)

I. Develop a paragraph. Your paragraph must include the following:

• Between 7-9 sentences
• A main idea sentence
• Each sentence must be developed, and checked for correct spelling and grammar
• Have at least three of the four different types of sentences (simple, complex, compound, compound-complex)
• Attach your pre-writing practice after the paragraph, to identify which sentences are major and minor detail sentence

Supporting Details

Earlier we covered what a main idea sentence was: a sentence that names the topic, and allows the reader to understand the focus of the paragraph to follow. It is logical then that the rest of the sentences in the paragraph support the main idea sentence. Support means that they either explain something about the topic, or they offer an example.

We’ve examined the relationship between a text’s thesis statement and its overall organization through the idea of topic sentences in body paragraphs. But of course body paragraphs have a lot more “stuff” in them than just topic sentences. This section will examine in more detail what that “stuff” is made of.

First, watch this video that details the relationship between a topic sentence and supporting details, using the metaphor of a house. The video establishes the difference between major and minor details, which will be useful to apply in coming discussions. (The video has instrumental guitar for audio, but no spoken words, so it can be watched without sound if desired.)

The following image shows the visual relationship between the overall thesis, topic sentences, and supporting ideas:

This next image shows where a topic sentence might reside in the paragraph, in relation to the rest of the supporting details:

In #5 of the sequence above, the topic sentence is rephrased between the opening and closing of the paragraph, to reinforce the concept more strongly.

Point, Illustration, Explanation (P.I.E.)

Many authors use the PIE format to structure their essays. PIE = point, illustration, explanation to structure their body paragraph and support their thesis. The point furthers a thesis or claim and is the same as the main idea, the illustration provides support for the point, and the explanation tells the audience why the evidence provided furthers the point and/or the thesis.

For example, in his argument against the +/- grading system at Radford, student-writer Tareq Hajj makes the Point that “Without the A+, students with high grades in the class would be less motivated to work even harder in order to increase their grades.”

He Illustrates with a quote from a professor who argues, “‘(students) have less incentive to try’” (Fesheraki, 2013).

Hajj then Explains that “not providing [the most motivated students] with additional motivation of a higher grade … is inequitable.”

Through his explanation, Hajj links back to his claim that “A plus-minus grading scale … should not be used at Radford University” because, as he explains, it is “inequitable.” The PIE structure of his paragraph has served to support his thesis.

All Claims Need Evidence

Ever heard the phrase “everyone is entitled to his opinion”? It is indeed true that people are free to believe whatever they wish. However, the mere fact that a person believes something is not an argument in support of a position. If a text’s goal is to communicate effectively, it must provide valid explanations and sufficient and relevant evidence to convince its audience to accept that position. In other words, “every author is entitled to his opinion, but no author is entitled to have his opinion go unchallenged.”

What are the types of evidence?

Any text should provide illustrations for each of its points, but it is especially important to provide reliable evidence in an academic argument. This evidence can be based on primary source material or data (the author’s own experience and/or interviews, surveys, polls, experiments, that she may have created and administered). Evidence can also stem from secondary source material or data (books, journals, newspapers, magazines, websites or surveys, experiments, statistics, polls, and other data collected by others).

Let’s say, for example, that you are reading an argument that college instructors should let students use cell phones in class. Primary source material might include a survey the author administered that asks students if policies forbidding cell phone usage actually stop them from using their phones in class. Secondary sources might include articles about the issue from Faculty Focus or The Chronicle of Higher Education .

Logos, Ethos, Pathos

Writers are generally most successful with their audiences when they can skillfully and appropriately balance the three core types of appeals. These appeals are referred to by their Greek names: logos (the appeal to logic), pathos (the appeal to emotion), and ethos (the appeal to authority). All of these are used in one way or another in your body paragraphs, particularly as it relates to the support or information in the paragraph.

Logical Appeals

Authors using logic to support their claims will include a combination of different types of evidence. These include the following:

• established facts
• case studies
• experiments
• analogies and logical reasoning
• citation of recognized experts on the issue

Authoritative Appeals

Authors using authority to support their claims can also draw from a variety of techniques. These include the following:

• personal anecdotes
• illustration of deep knowledge on the issue
• testimony of those involved first-hand on the issue

Emotional Appeals

Authors using emotion to support their claims again have a deep well of options to do so. These include the following:

• impact studies

As you can see, there is some overlap on these lists. One technique might work simultaneously on multiple levels.

Most texts rely on one of the three as the primary method of support, but may also draw upon one or two others at the same time.

Check your understanding of supporting details by doing this quiz.

Exercise \(\PageIndex{6}\)

Read the paragraph below and find the main idea and supporting details.

My parents were very strict when I was growing up. My mother in particular was always correcting my behavior. One day when I forgot to look both ways when I was crossing the street, my mother made me go back home; she said that I could not go out at all if I could not be safe. My father was more concerned with my grades. Every night he would make me go to my room before I could watch television.

Let’s examine the pattern for this paragraph. The first sentence (1) presents the main idea, that my parents were strict. The second sentence (2) explains what I mean by “strict,” by saying that my mother was strict in correcting my behavior. The third sentence (3) offers an example of how she would correct my behavior. The fourth sentence (4) explains further, that my father was strict when it came to schoolwork, and then the fifth sentence (5) offers an example of how he was strict.

If we were going to diagram the paragraph above, it would look like this:

EXPLAIN (2)-___________________EXPLAIN (4)

EXAMPLE (3) EXAMPLE (5)

Major and Minor Supporting Details

One way to talk about whether a sentence directly supports the main idea (the second level), or indirectly supports the main idea (the third level) is to call them MAJOR detail sentences or MINOR detail sentences. Major details directly explain something about the topic, while minor details offer examples for the Major detail that came right before.

Exercise \(\PageIndex{7}\)

Read the paragraphs, and then identify each sentence as either a main idea, a major detail, or a minor detail sentence.

Single parents have to overcome many obstacles to return to school. If the child is very young, finding quality babysitting can be difficult. Many babysitters are unreliable and that can mean that the parent has to miss many classes, which can hurt their grades. It is also hard to find enough time to study. Children require a lot of attention and are also noisy, and that can interfere with a parent's ability to complete their homework. Finally, raising children is expensive. Many single parents discover that they can’t meet the costs of both raising children and paying for tuition, books, and fees.

Sentence #1: Sentence #2: Sentence #3: Sentence #4: Sentence #5: Sentence #6: Sentence #7:

My grandmother turned 70 last year and celebrated by going skydiving. She said she always wanted to try and figured it was now or never. Many people think that when you get older you can no longer do fun things, but this is not true. The senior center in town offers dance lessons and also takes groups to the art museum. The classes are always full because so many people want to try new things. Towns are even developing senior living communities around activities such as golf and tennis. Those communities are very popular because people like to live with others who share their interests.

Sentence #1: Sentence #2: Sentence #3: Sentence #4: Sentence #5: Sentence #6: Sentence #7

Exercise \(\PageIndex{8}\)

Below you will find several main idea sentences. Provide appropriate supporting sentences following the pattern of Major-Minor-Major- Minor.

1. It is not a good idea to watch a lot of television. Major: Minor: Major: Minor:

2. Coaches have good reasons to be firm with the players on their team. Major: Minor: Major: Minor:

3. Many people believe it is a bad idea to spank children. Major: Minor: Major: Minor:

4. There are several steps I can take to be successful in college.

Major: Minor: Major: Minor:

Reading-Writing Connection: Supporting Details

Exercise \(\PageIndex{9}\)

Return to the Thesis exercise you did previously. As part of that exercise, you identified two topic sentences from your selected reading. Now, look more closely at the paragraphs where those two topic sentences came from.

• Write a paragraph that identifies the type of support that each paragraph from the reading uses to reinforce each of those two topic sentences. Are they narrative or personal examples? Are they facts or statistics? Are they quotes or paraphrases from research materials?
• Write another paragraph that compares the effectiveness of the supporting claims of one of the selected paragraphs against the other one. Which seems more successful in its goal? Why do you feel that way?

V. Process and Organization

5.2 Writing Paragraphs

Kathryn Crowther; Lauren Curtright; Nancy Gilbert; Barbara Hall; Tracienne Ravita; Kirk Swenson; and Terri Pantuso

Once you decide on a method for organizing your essay, you’ll want to start drafting your paragraphs. Think of your paragraphs as links in a chain where coherence and continuity are key. Imagine reading one long block of text, with each idea blurring into the next. You are likely to lose interest in a piece of writing that is disorganized and spans many pages without breaks. Paragraphs separate ideas into logical, manageable chunks, each paragraph focusing on only one main idea and presenting coherent sentences to support that one point. Because all the sentences in one paragraph support the same point, a paragraph may stand on its own. For most types of informative or persuasive academic writing, writers find it helpful to think of the paragraph analogous to an essay, as each is controlled by a main idea or point, and that idea is developed by an organized group of more specific ideas. Thus, the thesis of the essay is analogous to the topic sentence of a paragraph, just as the supporting sentences in a paragraph are analogous to the supporting paragraphs in an essay.

In essays, each supporting paragraph adds another related main idea to support the writer’s thesis, or controlling idea. Each related supporting idea is developed with facts, examples, and other details that explain it. By exploring and refining one idea at a time, writers build a strong case for their thesis. Effective paragraphing makes the difference between a satisfying essay that readers can easily process and one that requires readers to mentally organize the piece themselves. Thoughtful organization and development of each body paragraph leads to an effectively focused, developed, and coherent essay.

An effective paragraph contains three main parts:

• a topic sentence
• body, supporting sentences
• a concluding sentence

In informative and persuasive writing, the topic sentence is usually the first or second sentence of a paragraph and expresses its main idea, followed by supporting sentences that help explain, prove, or enhance the topic sentence. In narrative and descriptive paragraphs, however, topic sentences may be implied rather than explicitly stated, with all supporting sentences working to create the main idea. If the paragraph contains a concluding sentence, it is the last sentence in the paragraph and reminds the reader of the main point by restating it in different words.

Creating Focused Paragraphs with Topic Sentences

The foundation of a paragraph is the topic sentence which expresses the main idea or point of the paragraph. A topic sentence functions in two ways: it clearly refers to and supports the essay’s thesis, and it indicates what will follow in the rest of the paragraph. As the unifying sentence for the paragraph, it is the most general sentence, whereas all supporting sentences provide different types of more specific information such as facts, details, or examples.

An effective topic sentence has the following characteristics:

• A topic sentence provides an accurate indication of what will follow in the rest of the paragraph.

Weak Example

First, we need a better way to educate students.

Explanation: The claim is vague because it does not provide enough information about what will follow and it is too broad to be covered effectively in one paragraph.

Stronger Example

Creating a national set of standards for math and English education will improve student learning in many states.

Explanation: The sentence replaces the vague phrase “a better way” and leads readers to expect supporting facts and examples as to why standardizing education in these subjects might improve student learning in many states.

• A good topic sentence is the most general sentence in the paragraph and thus does not include supporting details.

Salaries should be capped in baseball for many reasons, most importantly so we don’t allow the same team to win year after year.

Explanation: This topic sentence includes a supporting detail that should be included later in the paragraph to back up the main point.

Introducing a salary cap would improve the game of baseball for many reasons.

Explanation: This topic sentence omits the additional supporting detail so that it can be expanded upon later in the paragraph, yet the sentence still makes a claim about salary caps – improvement of the game.

• A good topic sentence is clear and easy to follow.

In general, writing an essay, thesis, or other academic or nonacademic document is considerably easier and of much higher quality if you first construct an outline, of which there are many different types.

Explanation: The confusing sentence structure and unnecessary vocabulary bury the main idea, making it difficult for the reader to follow the topic sentence.

Most forms of writing can be improved by first creating an outline.

Explanation: This topic sentence cuts out unnecessary verbiage and simplifies the previous statement, making it easier for the reader to follow. The writer can include examples of what kinds of writing can benefit from outlining in the supporting sentences.

Location of Topic Sentences

As previously discussed, a topic sentence can appear anywhere within a paragraph depending upon the mode of writing, or it can be implied such as in narrative or descriptive writing. In college-level expository or persuasive writing, placing an explicit topic sentence at the beginning of each paragraph (the first or second sentence) makes it easier for readers to follow the essay and for writers to stay on topic, but writers should be aware of variations and maintain the flexibility to adapt to different writing projects. The following examples illustrate varying locations for the topic sentence. In each example, the topic sentence is underlined.

Topic Sentence Begins the Paragraph (General to Specific)

After reading the new TV guide this week I wondered why we are still being bombarded with reality shows, a plague that continues to darken our airwaves. Along with the return of viewer favorites, we are to be cursed with yet another mindless creation. Prisoner follows the daily lives of eight suburban housewives who have chosen to be put in jail for the purposes of this fake psychological experiment. A preview for the first episode shows the usual tears and tantrums associated with reality television. I dread to think what producers will come up with next season and hope that other viewers will express their criticism. These producers must stop the constant stream of meaningless shows without plotlines. We’ve had enough reality television to last us a lifetime.

The first sentence tells readers that the paragraph will be about reality television shows, and it expresses the writer’s distaste for these shows through the use of the word bombarded . Each of the following sentences in the paragraph supports the topic sentence by providing further information about a specific reality television show and why the writer finds it unappealing. The final sentence is the concluding sentence. It reiterates the main point that viewers are bored with reality television shows by using different words from the topic sentence.

Paragraphs that begin with the topic sentence move from the general to the specific. They open with a general statement about a subject (reality shows) and then discuss specific examples (the reality show Prisoner ). Most academic essays contain the topic sentence at the beginning of the first paragraph. However, when utilizing a specific to general method, the topic sentence may be located later in the paragraph.

Topic Sentence Ends the Paragraph (Specific to General)

Last year, a cat traveled 130 miles to reach its family who had moved to another state and had left their pet behind. Even though it had never been to their new home, the cat was able to track down its former owners. A dog in my neighborhood can predict when its master is about to have a seizure. It makes sure that he does not hurt himself during an epileptic fit. Compared to many animals, our own senses are almost dull.

The last sentence of this paragraph is the topic sentence. It draws on specific examples (a cat that tracked down its owners and a dog that can predict seizures) and then makes a general statement that draws a conclusion from these examples (animals’ senses are better than humans’). In this case, the supporting sentences are placed before the topic sentence, and the concluding sentence is the same as the topic sentence. This technique is frequently used in persuasive writing. The writer produces detailed examples as evidence to back up his or her point, preparing the reader to accept the concluding topic sentence as the truth.

When the Topic Sentence Appears in the Middle of the Paragraph

For many years, I suffered from severe anxiety every time I took an exam. Hours before the exam, my heart would begin pounding, my legs would shake, and sometimes I would become physically unable to move. Last year, I was referred to a specialist and finally found a way to control my anxiety—breathing exercises. It seems so simple, but by doing just a few breathing exercises a couple of hours before an exam, I gradually got my anxiety under control. The exercises help slow my heart rate and make me feel less anxious. Better yet, they require no pills, no equipment, and very little time. It’s amazing how just breathing correctly has helped me learn to manage my anxiety symptoms.

In this paragraph, the underlined sentence is the topic sentence. It expresses the main idea—that breathing exercises can help control anxiety. The preceding sentences enable the writer to build up to his main point (breathing exercises can help control anxiety) by using a personal anecdote (how he used to suffer from anxiety). The supporting sentences then expand on how breathing exercises help the writer by providing additional information. The last sentence is the concluding sentence and restates how breathing can help manage anxiety. Placing a topic sentence in the middle of a paragraph is often used in creative writing. If you notice that you have used a topic sentence in the middle of a paragraph in an academic essay, read through the paragraph carefully to make sure that it contains only one major topic.

Implied Topic Sentences

Some well-organized paragraphs do not contain a topic sentence at all, a technique often used in descriptive and narrative writing. Instead of being directly stated, the main idea is implied in the content of the paragraph, as in the following narrative paragraph.

Example of Implied Topic Sentence

Heaving herself up the stairs, Luella had to pause for breath several times. She let out a wheeze as she sat down heavily in the wooden rocking chair. Tao approached her cautiously, as if she might crumble at the slightest touch. He studied her face, like parchment, stretched across the bones so finely he could almost see right through the skin to the decaying muscle underneath. Luella smiled a toothless grin.

Although no single sentence in this paragraph states the main idea, the entire paragraph focuses on one concept—that Luella is extremely old. The topic sentence is thus implied rather than stated so that all the details in the paragraph can work together to convey the dominant impression of Luella’s age. In a paragraph such as this one, an explicit topic sentence would seem awkward and heavy-handed. Implied topic sentences work well if the writer has a firm idea of what he or she intends to say in the paragraph and sticks to it. However, a paragraph loses its effectiveness if an implied topic sentence is too subtle or the writer loses focus.

Developing Paragraphs

If you think of a paragraph as a sandwich, the supporting sentences are the filling between the bread. They make up the body of the paragraph by explaining, proving, or enhancing the controlling idea in the topic sentence. The overall method of development for paragraphs depends upon the essay as a whole and the purpose of each paragraph; thus paragraphs may be developed by using examples, description, narration, comparison and contrast, definition, cause and effect, classification and division. A writer may use one method or combine several methods.

Writers often want to know how many words a paragraph should contain, and the answer is that a paragraph should develop the idea, point, or impression completely enough to satisfy the writer and readers. Depending on their function, paragraphs can vary in length from one or two sentences, to over a page; however, in most college assignments, successfully developed paragraphs usually contain approximately one hundred to two hundred and fifty words and span one-fourth to two-thirds of a typed page. A series of short paragraphs in an academic essay can seem choppy and unfocused, whereas paragraphs that are one page or longer can tire readers. Giving readers a paragraph break on each page helps them maintain focus.

This advice does not mean, of course, that composing a paragraph of a particular number of words or sentences guarantees an effective paragraph. Writers must provide enough supporting sentences within paragraphs to develop the topic sentence and simultaneously carry forward the essay’s main idea.

For example, in a descriptive paragraph about a room in the writer’s childhood home, a length of two or three sentences is unlikely to contain enough details to create a picture of the room in the reader’s mind, and it will not contribute in conveying the meaning of the place. In contrast, a half page paragraph, full of carefully selected vivid, specific details and comparisons, provides a fuller impression and engages the reader’s interest and imagination. In descriptive or narrative paragraphs, supporting sentences present details and actions in vivid, specific language in objective or subjective ways, appealing to the readers’ senses to make them see and experience the subject. In addition, some sentences writers use make comparisons that bring together or substitute the familiar with the unfamiliar, thus enhancing and adding depth to the description of the incident, place, person, or idea.

In a persuasive essay about raising the wage for certified nursing assistants, a paragraph might focus on the expectations and duties of the job, comparing them to that of a registered nurse. Needless to say, a few sentences that simply list the certified nurse’s duties will not give readers a complete enough idea of what these healthcare professionals do. If readers do not have plenty of information about the duties and the writer’s experience in performing them for what she considers inadequate pay, the paragraph fails to do its part in convincing readers that the pay is inadequate and should be increased.

In informative or persuasive writing, a supporting sentence usually offers one of the following:

• Reason:  The refusal of the baby boom generation to retire is contributing to the current lack of available jobs.
• Fact: Many families now rely on older relatives to support them financially.
• Statistic: Nearly 10 percent of adults are currently unemployed in the United States.
• Quotation: “We will not allow this situation to continue,” stated Senator Johns.
• Example: Last year, Bill was asked to retire at the age of fifty-five.

The type of supporting sentence you choose will depend on what you are writing and why you are writing. For example, if you are attempting to persuade your audience to take a particular position, you should rely on facts, statistics, and concrete examples, rather than personal opinions. Personal testimony in the form of an extended example can be used in conjunction with the other types of support.

Consider the elements in the following paragraph.

Example Persuasive Paragraph

Topic sentence: There are numerous advantages to owning a hybrid car.

Sentence 1 (statistic): First, they get 20 percent to 35 percent more miles to the gallon than a fuel- efficient gas-powered vehicle.

Sentence 2 (fact): Second, they produce very few emissions during low speed city driving.

Sentence 3 (reason): Because they do not require gas, hybrid cars reduce dependency on fossil fuels, which helps lower prices at the pump.

Sentence 4 (example): Alex bought a hybrid car two years ago and has been extremely impressed with its performance.

Sentence 5 (quotation): “It’s the cheapest car I’ve ever had,” she said. “The running costs are far lower than previous gas powered vehicles I’ve owned.”

Concluding sentence: Given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

Sometimes the writing situation does not allow for research to add specific facts or other supporting information, but paragraphs can be developed easily with examples from the writer’s own experience.

Farheya, a student in a freshman English Composition class, quickly drafted an essay during a timed writing assignment in class. To practice improving paragraph development, she selected the body paragraph below to add support:

Example of Original Body Paragraph

Topic: Would you be better off if you didn’t own a television? Discuss.

Lack of ownership of a television set is also a way to preserve innocence, and keep the exposure towards anything inappropriate at bay. From simply watching a movie, I have seen things I shouldn’t have, no matter how fast I switch the channel. Television shows not only display physical indecency, but also verbal. Many times movies do voice-overs of profane words, but they also leave a few words uncensored. Seeing how all ages can flip through and see or hear such things make t.v. toxic for the mind, and without it I wouldn’t have to worry about what I may accidentally see or hear.

The original paragraph identifies two categories of indecent material, and there is mention of profanity to provide a clue as to what the student thinks is indecent. However, the paragraph could use some examples to make the idea of inappropriate material clearer. Farheya considered some of the television shows she had seen and made a few changes.

Example of Revised Body Paragraph

Not owning a television set would also be a way to preserve innocence and keep my exposure to anything inappropriate at bay. While searching for a program to view, I have seen things I shouldn’t have, no matter how fast I switched the channel. The synopsis of Euro Trip, which describes high school friends traveling across Europe, leads viewers to think that the film is an innocent adventure; however; it is filled with indecency, especially when the students reach Amsterdam. The movie Fast and Furious has the same problem since the women are all half-naked in half tops and mini-skirts or short- shorts. Television shows not only display physical indecency, but also verbal. Many television shows have no filters, and the characters say profane words freely. On Empire, the main characters Cookie and Lucious Lyon use profane words during their fights throughout entire episodes. Because The Big Bang Theory is a show about a group of science geeks and their cute neighbor, viewers might think that these science geniuses’ conversations would be about their current research or other science topics. Instead, their characters regularly engage in conversations about their personal lives that should be kept private. The ease of flipping through channels and seeing or hearing such things makes t.v. toxic for the mind, and without a television I wouldn’t have to worry about what I may accidentally see or hear.

Farheya’s addition of a few examples helps to convey why she thinks she would be better off without a television.

Concluding Sentences

An effective concluding sentence draws together all the ideas raised in your paragraph. It reminds readers of the main point—the topic sentence—without restating it in exactly the same words. Using the hamburger example, the top bun (the topic sentence) and the bottom bun (the concluding sentence) are very similar. They frame the “meat” or body of the paragraph.

Compare the topic sentence and concluding sentence from the first example on hybrid cars:

Topic Sentence: There are many advantages to owning a hybrid car.

Concluding Sentence: Given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

Notice the use of the synonyms advantages and benefits . The concluding sentence reiterates the idea that owning a hybrid is advantageous without using the exact same words. It also summarizes two examples of the advantages covered in the supporting sentences: low running costs and environmental benefits.

Writers should avoid introducing any new ideas into a concluding sentence because a conclusion is intended to provide the reader with a sense of completion. Introducing a subject that is not covered in the paragraph will confuse readers and weaken the writing.

A concluding sentence may do any of the following:

• Restate the main idea.

Childhood obesity is a growing problem in the United States.

• Summarize the key points in the paragraph

A lack of healthy choices, poor parenting, and an addiction to video games are among the many factors contributing to childhood obesity.

• Draw a conclusion based on the information in the paragraph.

These statistics indicate that unless we take action, childhood obesity rates will continue to rise.

• Make a prediction, suggestion, or recommendation about the information in the paragraph.

Based on this research, more than 60 percent of children in the United States will be morbidly obese by the year 2030 unless we take evasive action.

• Offer an additional observation about the controlling idea.

Childhood obesity is an entirely preventable tragedy.

Paragraph Length

Although paragraph length is discussed in the section on developing paragraphs with supporting sentences, some additional reminders about when to start a new paragraph may prove helpful to writers:

• If a paragraph is over a page long, consider providing a paragraph break for readers. Look for a logical place to divide the paragraph; then revise the opening sentence of the second paragraph to maintain coherence.
• A series of short paragraphs can be confusing and choppy. Examine the content of the paragraphs and combine ones with related ideas or develop each one further.
• When dialogue is used, begin a new paragraph each time the speaker changes.
• Begin a new paragraph to indicate a shift in subject, tone, or time and place.

Improving Paragraph Coherence

A strong paragraph holds together well, flowing seamlessly from the topic sentence into the supporting sentences and on to the concluding sentence. To help organize a paragraph and ensure that ideas logically connect to one another, writers use a combination of elements:

• A clear organizational pattern: chronological (for narrative writing and describing processes), spatial (for descriptions of people or places), order of importance, general to specific (deductive), specific to general (inductive)
• Transitional words and phrases: These connecting words describe a relationship between ideas.
• Repetition of ideas: This element helps keep the parts of the paragraph together by maintaining focus on the main idea, so this element reinforces both paragraph coherence and unity.

In the following example, notice the use of transitions ( bolded ) and key words ( underlined ):

Example of Transition Words

Owning a hybrid car benefits both the owner and the environment . First , these cars get 20 percent to 35 percent more miles to the gallon than a fuel-efficient gas-powered vehicle. Second , they produce very few emissions during low speed city driving. Because they do not require gas, hybrid cars reduce dependency on fossil fuels, which helps lower prices at the pump. Alex bought a hybrid car two years ago and has been extremely impressed with its performance. “It’s the cheapest car I’ve ever had,” she said. “The running costs are far lower than previous gas-powered vehicles I’ve owned.” Given the low running costs and environmental benefits of owning a hybrid car , it is likely that many more people will follow Alex’s example in the near future.

Words such as first and second are transition words that show sequence or clarify order. They help organize the writer’s ideas by showing that he or she has another point to make in support of the topic sentence. The transition word because is a transition word of consequence that continues a line of thought. It indicates that the writer will provide an explanation of a result. In this sentence, the writer explains why hybrid cars will reduce dependency on fossil fuels (because they do not require gas).

In addition to transition words, the writer repeats the word hybrid (and other references such as these cars , and they ), and ideas related to benefits to keep the paragraph focused on the topic and hold it together.

To include a summarizing transition for the concluding sentence, the writer could rewrite the final sentence as follows:

In conclusion, given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex’s example in the near future.

Although the phrase “in conclusion” certainly reinforces the idea of summary and closure, it is not necessary in this case and seems redundant, as the sentence without the phrase already repeats and summarizes the benefits presented in the topic sentence and flows smoothly from the preceding quotation. The second half of the sentence, in making a prediction about the future, signals a conclusion, also making the phrase “in conclusion” unnecessary. The original version of the concluding sentence also illustrates how varying sentence openings can improve paragraph coherence. As writers continue to practice and develop their style, they more easily make these decisions between using standard transitional phrases and combining the repetition of key ideas with varied sentence openings.

Table 5.2.1 provides some useful transition words and phrases to connect sentences within paragraphs as well as to connect body paragraphs:

Corresponding or related to two ideas. An analogy refers to a comparison made to the similarity between two items, ideas, events, and phenomena. Forrest Gump’s famous saying that “life is like a box of chocolates—you never know what you are going to get” is an example of an analogy.

A statement, usually one sentence, that summarizes an argument that will later be explained, expanded upon, and developed in a longer essay or research paper. In undergraduate writing, a thesis statement is often found in the introductory paragraph of an essay. The plural of thesis is theses .

Use of words, particularly referring to the overuse or redundancy of them.

Repeat, rehash, or restate something that has already been conveyed; to echo a sentiment or idea that was stated earlier in a different way or manner.

A short account or telling of an incident or story, either personal or historical; anecdotal evidence is frequently found in the form of a personal experience rather than objective data or widespread occurrence.
