What is an expository essay?

The expository essay is a genre of essay that requires the student to investigate an idea, evaluate evidence, expound on the idea, and set forth an argument concerning that idea in a clear and concise manner. This can be accomplished through comparison and contrast, definition, example, the analysis of cause and effect, etc.

Please note : This genre is commonly assigned as a tool for classroom evaluation and is often found in various exam formats.

The structure of the expository essay is held together by the following.

• A clear, concise, and defined thesis statement that occurs in the first paragraph of the essay.

It is essential that this thesis statement be appropriately narrowed to follow the guidelines set forth in the assignment. If the student does not master this portion of the essay, it will be quite difficult to compose an effective or persuasive essay.

• Clear and logical transitions between the introduction, body, and conclusion.

Transitions are the mortar that holds the foundation of the essay together. Without logical progression of thought, the reader is unable to follow the essay’s argument, and the structure will collapse.

• Body paragraphs that include evidential support.

Each paragraph should be limited to the exposition of one general idea. This will allow for clarity and direction throughout the essay. What is more, such conciseness creates an ease of readability for one’s audience. It is important to note that each paragraph in the body of the essay must have some logical connection to the thesis statement in the opening paragraph.

• Evidential support (whether factual, logical, statistical, or anecdotal).

Often times, students are required to write expository essays with little or no preparation; therefore, such essays do not typically allow for a great deal of statistical or factual evidence.

• A bit of creativity!

Though creativity and artfulness are not always associated with essay writing, it is an art form nonetheless. Try not to get stuck on the formulaic nature of expository writing at the expense of writing something interesting. Remember, though you may not be crafting the next great novel, you are attempting to leave a lasting impression on the people evaluating your essay.

• A conclusion that does not simply restate the thesis, but readdresses it in light of the evidence provided.

It is at this point of the essay that students will inevitably begin to struggle. This is the portion of the essay that will leave the most immediate impression on the mind of the reader. Therefore, it must be effective and logical. Do not introduce any new information into the conclusion; rather, synthesize and come to a conclusion concerning the information presented in the body of the essay.

A complete argument

Perhaps it is helpful to think of an essay in terms of a conversation or debate with a classmate. If I were to discuss the cause of the Great Depression and its current effect on those who lived through the tumultuous time, there would be a beginning, middle, and end to the conversation. In fact, if I were to end the exposition in the middle of my second point, questions would arise concerning the current effects on those who lived through the Depression. Therefore, the expository essay must be complete, and logically so, leaving no doubt as to its intent or argument.

The five-paragraph Essay

A common method for writing an expository essay is the five-paragraph approach. This is, however, by no means the only formula for writing such essays. If it sounds straightforward, that is because it is; in fact, the method consists of:

• an introductory paragraph
• three evidentiary body paragraphs
• a conclusion

Expository Essay: 3 Building Blocks to Propose an Idea and Defend It

by Dixie-Ann Belle | 0 comments

If you saw the words “expository essay” on a writing assignment, would your mind draw a blank? Would you immediately feel as if you had stumbled into unexplored territory?

Well there's good news.

This post is written by guest writer Dixie-Ann Belle. You can learn more about Dixie-Anne at the end of this article. Welcome Dixie-Ann! 

You might not realize it, but chances are this is not your first encounter with this type of essay. Once you have been writing essays in academic environments, you have probably already worked on expository writing.

In this article, I hope to help you recognize this essay type and understand the expository essay outline. Comprehending the building blocks is instrumental in knowing how to construct an exceptional expository essay.

Lay a Strong Foundation

Over the years, I have taught and tutored college students one on one as they write academic essays, in face to face classrooms and online, and I have noticed a pattern. They often approach essays in one of two ways.

Some consider them with apprehension and are fearful of making mistakes. Others feel confident that they have written many essays before and think they have already mastered expository writing.

Interestingly, it's the latter who often end up the most shaken when they realize that they are not as familiar as they think with this type of writing.

What I hope to instill in my students is that they should not feel intimidated whatever their situation or essay assignment.

I encourage them to make sure they understand the foundations of the expository essay structure. I try to get them to grasp the basic blocks that need to be there, and once they do, they have a good chance of crafting a substantial piece of writing.

What is an Expository Essay?

Students are typically assigned one of at least four types of essays: the persuasive/argumentative essay, the descriptive essay, the technical essay, or the expository essay.

Writing an expository essay is one of the most important and valuable skills for you to master.

According to the Purdue Online Writing Lab:

The expository essay is a genre of essay that requires the student to investigate an idea, evaluate evidence, expound on the idea, and set forth an argument concerning that idea in a clear and concise manner.

Keep in mind that your expository writing centers on giving your reader information about a given topic or process. Your goal is to inform, describe, or define the subject for your readers.

As you work to achieve this, your essay writing must be formal, objective, and concise. No matter what your discipline, it's almost guaranteed that you will be required to write this common type essay one day.

Some expository essay examples could include:

• Define the term ‘democracy'
• Compare and contrast the benefits of cable television vs streaming
• Outline the process that generates an earthquake
• Classify the different types of tourism
• Outline the aspects of a good fitness program

The possibilities are endless with expository writing, and it can cover a wide variety of topics and specialties.

3 Building Blocks of a Great Expository Essay

To make sure you're on the right track with this type of paper, it helps to understand the three building blocks of the expository essay format and how to apply them to the final expository essay structure .

1. Write an introduction

Most students know that an introductory paragraph should grab the interest of the reader. However, they might not realize that it should also provide context for the essay topic.

Ask yourself : What are you talking about in this essay? Why is this topic important? Some background details could help to establish the subject for your reader.

For example:

If you were writing an essay on the impact smartphones have on society, you might want to start with some information on the evolution of smartphones, the number of smartphones in society, the way people use the phones and more.

The introduction should start off with general information.

You then work your way down to the more specific and principal part of your introduction and the crown of your whole essay, the thesis statement.

What is the thesis statement?

Your thesis statement states in concise language what this essay is going to be about. It is one clear sentence which expresses the subject and the focus of this piece of writing. If there is a prompt, the thesis statement should directly answer that prompt.

Our smart phones topic might create a thesis statement like:  Smart phones have many positive impacts for adults in the business world.

Right away the reader has some idea of what's ahead.

2. Write your body paragraphs

With your thesis statement clear in your mind and your introduction setting the scene, it is time to write your body paragraphs.

Each body paragraph contains supporting information including factual evidence for your essay topic. Each paragraph should each focus on one idea.

Depending on your word count and the teacher requirements, you can write any number of body paragraphs, but there are usually at least three for a basic five paragraph essay.

Each body paragraph should start with a topic sentence. A topic sentence is one single statement that explains the point of the paragraph. It directly refers to your thesis statement and tells you what the body paragraph is going to be about.

Remember our smart phone thesis statement? You need something that will relate to that thesis sentence and will alert the reader to what is to come.

Here's one possibility: 

Smart phones can help increase productivity  for professional adults.

This topic sentence not only reminds us that you are talking about positive impacts for adults with smart phones, it now shows us what the following paragraph will cover.

The best body paragraphs will go on to include different types of details, all of which would support your topic sentence. A good abbreviation to encapsulate the different details is spelt TEEES.

The TEEES Body Paragraph Structure

Let's break down this abbreviation and explore the types of details you'll need in your body paragraphs

T: Topic sentence

You'll begin with your topic sentence establishing the purpose of this paragraph. We'll use our example from above:

Smartphones can help increase productivity for professional adults.

E: Explanation

This is where you expand on your topic and include additional supportive information.

If you were talking about smartphones and productivity, maybe you could mention what elements of the smartphone make it optimal for productivity.

E: Evidence

This is the information from reputable sources you researched for your topic. Here's where you can talk about all the information you have discovered from experts who have carefully studied this subject.

For our smartphone essay, perhaps you could mention a quote from a technology reporter who has been following the rise of smartphones for years.

E: Examples

This would be concrete subject matter to support your point.

Maybe here you can list some of the smartphone apps which have proven to increase productivity in the workplace.

S: Significant/Summarizing sentence

This is the last sentence in the body paragraph which summarizes your point and ends this part of your essay. There should be no doubt in the reader's mind that you have finished talking about your topic, and you are moving on to another in the next paragraph. Here's how we could conclude this paragraph on smartphones and productivity:

Smartphones have transformed the productivity of the modern workforce.

3. Write the conclusion

Once you have written your body paragraphs, you're in the home stretch. You have presented all of your points and supported them with the appropriate subject matter. Now you need to conclude.

A lot of students are confused by conclusions. Many of them have heard different rules about what is supposed to be included.

One of the main requirements to keep in mind when ending an expository essay is that you do not add new information.

This is not the time to throw in something you forgot in a previous body paragraph. Your conclusion is supposed to give a succinct recap of the points that came before.

Sometimes college students are instructed to re-state the thesis, and this puzzles them. It doesn't mean re-writing the thesis statement word for word. You should express your thesis statement in a new way.

For example, here's how you could approach the conclusion for our smartphone essay.

You've come up with three points to support your thesis statement, and you've explored these three points in your body paragraphs. After brainstorming, you might decide the benefits of smartphones in the workplace are improved productivity, better communication, and increased mobility.

Your conclusion is the time to remind your reader of these points with concise language. Your reader should be able to read the conclusion alone and still come away with the basic ideas of your essay.

Plan Your Essay Based on an Expository Essay Outline

While writing fiction, it is sometimes okay to “pants” it and just leap into writing your story.

When writing essays in academia, this is rarely a good idea. Planning your essay helps organize your ideas, helps you refine many of your points early on and saves time in the long run.

There are lots of great brainstorming techniques you can use to get your ideas together, but after that, it's time to create a topic to sentence outline.

There are three steps to creating your topic to sentence essay outline.

• Develop a powerful thesis statement. Remember, this is the overarching idea of your entire essay, so you have completed a significant step once you have one done.
• Come up with the ideas you would like to support your thesis statement.
• Based on your points, craft your topic sentences.

Here is an example of a topic to sentence outline:

Having these important foundation details completed is a great way to develop your essay as you build on each part. It is also an effective method to make sure you are on the right track.

Depending on your instructor (or tutor, if you have one), you can show your outline to them to get feedback before you launch into your entire essay.

Even if you don't have anyone to provide a critique, the outline can make it easier to revise how you will approach the rest of your paragraph essay.

You now have some firm foundations to help you as you construct your expository essay.

How do you organize an expository essay?  Let us know in the comments .

Take fifteen minutes to practice writing your own expository essay.

First, choose an expository writing assignment topic. If you can't think of one, use one of the expository essay examples below .  

• What are the nutritional elements of a healthy breakfast?
• What are some of the most influential types of music?
• Compare and contrast the benefits of electric and gas cars. 
• What are the major steps to planning a stress-free vacation?
• How do smartphones affect mental health?
• Define true love.

Craft a thesis statement about your topic. Then, write three topic sentences for your body paragraphs.

With the time you have left, start writing your essay. You might be surprised how much you can write in fifteen minutes when you have a clear outline for your essay!

When your time is up, share your outline and your essay in the Pro Practice Workshop here . After you post, please be sure to give feedback to your fellow writers.

Happy writing!

Expository Writing: Definition and Examples

Hannah Yang

Table of Contents

What is expository writing, what is an expository paragraph, expository writing examples, how prowritingaid can help you with expository composition.

One of the most common types of writing is expository writing. Whether you’re a student taking an English class or a professional trying to communicate to others in your field, you’ll need to use expository writing in your day-to-day work.

So, what exactly does this term mean?

The short answer is that expository writing refers to any writing designed primarily to explain or instruct.

Read on to learn the definition of expository writing as well as some examples of what this type of writing can look like.

Before we look at examples of expository writing, let’s start with a quick definition of what this term actually means.

Expository Writing Definition

The term expository writing refers to any writing that’s designed to explain something. We use the word expository to describe any passage of writing that’s supposed to present information and help you understand it in an objective way.

Some common examples of expository writing include academic essays, textbooks, instructional guides, and news reports. Good expository writing should be factual, objective, and clear.

To better understand what this term means, think about the difference between a scientific article, a short story, and an advertisement.

The scientific article is considered expository writing because its primary purpose is to explain a particular topic in more detail. It presents data, analyzes what that data means, and focuses on the facts.  

On the other hand, the short story isn’t considered expository writing, because its core purpose isn’t to explain or inform—instead, it’s probably trying to entertain you or to take you on a journey. Short stories are narrative writing.

Similarly, an advertisement isn’t expository writing because its core purpose isn’t to explain or inform—instead, it’s trying to persuade you to buy what it’s selling. Advertisements are persuasive writing.   

Here’s a quick rundown of what expository essays should and shouldn’t do.

An expository essay should:

Teach the reader about a particular topic

Focus on the facts

Follow a clearly organized structure

Present information and details from credible sources

An expository essay should not:

Try to change the reader’s mind about something

Present the author’s personal opinions

Include made-up narratives or stories

Follow experimental or nonlinear structures

An expository paragraph is exactly what it sounds like—a paragraph of expository writing.

A well-written expository paragraph should follow a specific format to make it as clear and easy to read as possible. Most expository paragraphs do the following things:

Start with a topic sentence, which explains what the paragraph will be about

Then, include 3 – 5 body sentences that provide supporting details for the topic sentence

Finally, wrap things up with a closing sentence that summarizes what the paragraph has said

Writing an expository paragraph is a great way to practice expository writing. That’s because the paragraph follows the same structure as a more complex expository essay, just on a smaller scale.

Most expository essays should follow this format:  

Start with an introductory paragraph that includes the thesis statement, which tells the reader the core statement of the essay

Then, include 3 – 5 body paragraphs that provide factual evidence to support the thesis statement

Finally, wrap things up with a concluding paragraph that summarizes what the body paragraphs and thesis statement said

You can see the similarities between the two formats. If you can write a fantastic expository paragraph, you’ll be well-prepared to move on to writing a full expository essay.

Example of Expository Paragraph

Here’s an example of an expository paragraph that follows the structure described above.

The leading cause of death in the United States is heart disease, which can be fatal if it leads to heart attack or cardiac arrest. Heart attacks occur when a blockage in the coronary artery prevents oxygenated blood from reaching the heart. Cardiac arrests occur when the heart stops pumping entirely, which prevents the patient from breathing normally. Both of these problems can be deadly, even in seemingly healthy people who don’t have noticeable risk factors. As a result, heart disease is an important problem that many doctors and scientists are researching.

Good writing = better grades

ProWritingAid will help you improve the style, strength, and clarity of all your assignments.

There are many ways you can present information in an expository essay. Here are four of the most popular ways, along with examples of each one.  

Problem and Solution Essay

A problem and solution essay presents the reader with a problem and then considers possible solutions to that problem. 

Here’s an example passage you might find in a problem and solution essay:

Among the many proposed solutions to rising carbon emissions, one promising possibility is carbon trapping. Scientists are figuring out how to pull carbon emissions out of the atmosphere and trap it in less harmful forms, such as by injecting carbon dioxide underground so it will turn to stone.

Compare and Contrast Essay

This type of essay takes two subjects and compares and contrasts them. It focuses on highlighting the differences and similarities between those two things.

Here’s an example passage of this type of expository writing:

Though country music and R&B music have very different sounds, they also share many similarities. For one thing, both types of music embody a specific cultural identity. For another, both genres trace their roots back to the 1920s, when the Victor Talking Machine Company signed singers from the American South.

Classification Essay

In a classification essay, you describe the categories within a certain group of things.  

Here’s an example passage you might find in a classification essay:

There are three ways in which artificial intelligence might become stronger than humans in the future: high speed, high collective intelligence, and high quality. A speed AI would be able to perform calculations and experience the world much faster than humans. A collective intelligence, like a hive mind, would be able to break down a complex task into several parts and pursue them simultaneously. Finally, a quality AI would simply be able to solve more complex problems than humans could.

Process Essay

In a process essay, you give the reader the steps for completing a specific process. This is similar to a how-to guide or an instruction manual.   

Here’s an example passage you might find in this type of expository writing:

Caramelize the chopped onions in a frying pan. When the onions have caramelized, mix in the bell peppers, mushrooms, and tomatoes and stir for 4 – 6 minutes or until all the ingredients have softened. If you want to add meat, you can add ground beef and cook for another 4 – 6 minutes. Season with salt and pepper to taste.  

Good expository writing should be easy to read. After all, the purpose of exposition is to explain things to your readers, and you won’t be able to accomplish that if they have trouble understanding your writing.

That’s why ProWritingAid can help you write an expository essay. The grammar checker can help you ensure your sentences flow well, you’re not missing any necessary punctuation, and all your words are precise and clear.

Good luck, and happy writing!

What is expository essay definition, usage, and literary examples, expository essay definition.

An  expository essay  [ik-SPOZ-ih-tohr-ee ess-ay] is an essay in which the writer researches a topic and uses evidence to inform their readers or clarify the topic. They can take many forms, including a how-to essay, an essay that defines something, or an essay that studies a problem and offers a solution.

The Five-Paragraph Model

Most expository essays follow the five-paragraph essay model:

• Introduction:  The introduction contains the thesis statement or main point of the essay. Here, the writer describes the subject and gives necessary  context .
• Body:  This section is usually three or more paragraphs and offers supporting evidence for the thesis.
• Conclusion:  The conclusion revisits the thesis and summarizes the writer’s main points.

Types of Expository Essays

There are several types of expository essays that can be written.

• Cause and Effect:  These essays question why something happened and the outcome of that occurrence. For example, an essay of this type might question why there’s a large homeless population in Seattle and what effects it has on the city and its citizens.
• Classification:  These break a broad subject down into several, in-depth subcategories. A classification essay might study the various kinds of movies, define genres, and break the most common genres down by subgenre (for example, action thriller and action adventure as subgenres of the action genre).
• Compare and Contrast:  These essays lay out the similarities and differences of at least two subjects. One such essay might compare two different novels by the same author. These essays can explore the pros and cons of different choices as well, like living in the city versus living in the country.
• Definition:  As indicated, a definition essay describes or defines something. For example, it might define the internet and provide a detailed explanation of how it works.
• How-To:  Also called a process essay, a how-to essay gives the reader steps for creating or doing something. For example, a process essay might walk its reader through setting a table, step by step.
• Problem and Solution:  This type of essay explores a problem and, using evidential support, offers potential solutions. For example, a writer might consider the example of Seattle’s homeless population, cite a solution that other cities have used successfully, and propose that same solution for Seattle.

Other Forms of Expository Writing

In addition to the aforementioned, there are other uses for expository writing. Most commonly:

• Newspaper articles
• Encyclopedic entries
• Manuals/assembly instructions

Expository vs. Argumentative Essays

Expository essays are like argumentative essays in that they both require research. Unlike argumentative essays, expository essays are meant to inform their audience rather than persuade it.

Argumentative essays are often controversial and contain the writer’s personal opinions, whereas expository essays give factual information and explore a topic from many  perspectives . Educational spheres often use expository essays to test writing ability, reading comprehension, and/or the writer’s understanding of a topic.

Examples of Expository Essays

1. Susan Sontag, “Notes on ‘Camp’”

This is a definition essay that explores the meaning and usage of the slang word  camp . When she wrote the essay in 1964, people used the word to describe a person or thing as exaggerated, effeminate, or theatrical. Sontag suggests that camp isn’t a solid concept but rather a sensibility, and she acknowledges its connection to contemporary gay culture. Her definition of camp is given in the following passage:

[Camp] is not a natural mode of sensibility, if there be any such. Indeed the essence of Camp is its love of the unnatural: of artifice and exaggeration. And Camp is esoteric–something of a private code, a badge of identity even, among small urban cliques.

2. David Foster Wallace, “Consider the Lobster”

Herein, Wallace reviews the 2003 Main Lobster Festival and questions the morality of boiling lobsters alive. He examines the problem from all facets, including whether a lobster feels pain, without directly asserting his opinion. After descriptions of the festival, physical properties of lobsters, and the common use of the crustaceans, Wallace poses the main question of the essay:

So then here is a question that’s all but unavoidable at the World’s Largest Lobster Cooker, and may arise in the kitchens across the U.S. Is it all right to boil a sentient creature alive just for our gustatory pleasure? A related set of concerns: Is the previous question irksomely PC or sentimental? What does “all right” even mean in this context? Is it all just a matter of individual choice?

3. Rebecca Solnit, “The Longest War”

From Solnit’s 2014 book of essays,  Men Explain Things to Me , “The Longest War” explores issues of male violence against women. Solnit uses both statistical and  anecdotal  evidence to inform her audience of the issue, which supports some of her argumentative essays that appear later in the book:

[T]hough a rape is reported only every 6.2 minutes in this country, the estimated total is perhaps five times as high. Which means that there may be very nearly a rape a minute in the United States. It all adds up to tens of millions of rape victims. A significant portion of the women you know are survivors.

What is an Expository Essay?

The expository essay is a genre of essay that requires the student to investigate an idea, evaluate evidence, expound on the idea, and set forth an argument concerning that idea in a clear and concise manner. This can be accomplished through comparison and contrast, definition, example, the analysis of cause and effect, etc.

Please note : This genre is commonly assigned as a tool for classroom evaluation and is often found in various exam formats.

The structure of the expository essay is held together by the following:

A clear, concise, and defined thesis statement that occurs in the first paragraph of the essay.

It is essential that this thesis statement be appropriately narrowed to follow the guidelines set forth in the assignment. If the student does not master this portion of the essay, it will be quite difficult to compose an effective or persuasive essay.

Clear and logical transitions between the introduction, body, and conclusion.

Transitions are the mortar that holds the foundation of the essay together. Without logical progression of thought, the reader is unable to follow the essay’s argument, and the structure will collapse.

Body paragraphs that include evidential support.

Each paragraph should be limited to the exposition of one general idea. This will allow for clarity and direction throughout the essay. What is more, such conciseness creates an ease of readability for one’s audience. It is important to note that each paragraph in the body of the essay must have some logical connection to the thesis statement in the opening paragraph.

Evidential support (whether factual, logical, statistical, or anecdotal).

Often times, students are required to write expository essays with little or no preparation; therefore, such essays do not typically allow for a great deal of statistical or factual evidence.

A bit of creativity!

Though creativity and artfulness are not always associated with essay writing, it is an art form nonetheless. Try not to get stuck on the formulaic nature of expository writing at the expense of writing something interesting. Remember, though you may not be crafting the next great novel, you are attempting to leave a lasting impression on the people evaluating your essay.

A conclusion that does not simply restate the thesis, but readdresses it in light of the evidence provided.

It is at this point of the essay that students will inevitably begin to struggle. This is the portion of the essay that will leave the most immediate impression on the mind of the reader. Therefore, it must be effective and logical. Do not introduce any new information into the conclusion; rather, synthesize and come to a conclusion concerning the information presented in the body of the essay.

A Complete Argument

Perhaps it is helpful to think of an essay in terms of a conversation or debate with a classmate. If I were to discuss the cause of the Great Depression and its current effect on those who lived through the tumultuous time, there would be a beginning, middle, and end to the conversation. In fact, if I were to end the exposition in the middle of my second point, questions would arise concerning the current effects on those who lived through the Depression. Therefore, the expository essay must be complete, and logically so, leaving no doubt as to its intent or argument.

The Five-Paragraph Essay

A common method for writing an expository essay is the five-paragraph approach. This is, however, by no means the only formula for writing such essays. If it sounds straightforward, that is because it is; in fact, the method consists of:

• an introductory paragraph
• three evidentiary body paragraphs
• a conclusion

Expository Essay

Definition of expository essay.

Expose means to uncover or lay something bare, or to discover something in a way that others know what it is. Expository is derived from exposition , which is a noun of ‘expose.’ An expository essay is a genre of writing which tends to explain, illustrate, clarify, or explicate something in a way that it becomes clear for readers. Therefore, it could be an investigation, evaluation, or even argumentation about an idea for clarification.

Types of Expository Essay

Expository essay is further divided into five major categories .

• Descriptive Essay : A descriptive essay describes something, some place, some experience, or some situation through sensory information.
• Process Essay : A process essay explains or shows a process of making or doing something.
• Comparison Essay : A comparison essay makes comparison and contrasts between two things.
• Cause/Effect Essay : A cause and effect essay finds out the cause of something and then its effects on something else.
• Problem/Solution Essay : A problem/solution essay presents a problem and its solution for readers.

Difference Between an Expository Essay and an Argumentative Essay

As is clear, an expository essay is an exposition, explanation, investigation, or illustration for the purpose of clarification, therefore, its tone is often kept neutral. However, in an argumentative essay , a clear position about something is taken before the argument is presented. There is no issue of objectivity or neutrality.

Examples of Expository Essay in Literature

Example #1: how chinese mothers are superior (by amy chua).

“I’m using the term ‘Chinese mother’ loosely. I know some Korean, Indian, Jamaican, Irish and Ghanaian parents who qualify too. Conversely, I know some mothers of Chinese heritage, almost always born in the West, who are not Chinese mothers, by choice or otherwise. I’m also using the term ‘Western parents’ loosely. Western parents come in all varieties. All the same, even when Western parents think they’re being strict, they usually don’t come close to being Chinese mothers. For example, my Western friends who consider themselves strict make their children practice their instruments 30 minutes every day. An hour at most. For a Chinese mother, the first hour is the easy part. It’s hours two and three that get tough.”

This is an excerpt from a comparison/ contrast essay by Amy Chua, which explains how mothers are different in different cultures. This paragraph compares mothers from Chinese, Iranian, Jamaican, and Irish contexts .

Example #2: Learning to Read (by Malcolm X)

“It was because of my letters that I happened to stumble upon starting to acquire some kind of a homemade education. I became increasingly frustrated at not being able to express what I wanted to convey in letters that I wrote, especially those to Mr. Elijah Muhammad. In the street, I had been the most articulate hustler out there. I had commanded attention when I said something. But now , trying to write simple English, I not only wasn’t articulate, I wasn’t even functional. How would I sound writing in slang , the way I would say it, something such as, ‘Look, daddy , let me pull your coat about a cat, Elijah Muhammad — ‘ Many who today hear me somewhere in person, or on television, or those who read something I’ve said, will think I went to school far beyond the eighth grade. This impression is due entirely to my prison studies.”

This passage has been taken from a process essay. In this essay, Malcolm X tells the process of his learning. In this paragraph, he gives full detail how he learns letters.

Example #3: Summer Ritual (by Ray Bradbury)

“About seven o’clock you could hear the chairs scraping from the tables, someone experimenting with a yellow-toothed piano , if you stood outside the dining-room window and listened. Matches being struck, the first dishes bubbling in the suds and tinkling on the wall racks, somewhere, faintly, a phonograph playing. And then as the evening changed the hour, at house after house on the twilight streets, under the immense oaks and elms , on shady porches, people would begin to appear, like those figures who tell good or bad weather in rain -or-shine clocks. Uncle Bert, perhaps Grandfather, then Father, and some of the cousins; the men all coming out first into the syrupy evening, blowing smoke, leaving the wSWomen’s voices behind in the cooling-warm kitchen to set their universe aright. Then the first male voices under the porch brim, the feet up, the boys fringed on the worn steps or wooden rails where sometime during the evening something, a boy or a geranium pot, would fall off.”

This is an example of a passage from a descriptive essay. It has full description which tells us about sounds and colors; a type of sensory information.

The primary goal of expository writing is to explain or clarify a concept, process, or phenomenon using evidence, examples, and logical reasoning. Unlike persuasive or argumentative essays, the purpose of an expository essay is not to convince the reader of a particular viewpoint or opinion, but rather to provide clear and concise information.

The main objectives of expository writing are:

• Informing: Expository writing aims to educate and provide readers with new or valuable information. It seeks to convey facts, details, concepts, or ideas about a topic in a straightforward and concise manner.
• Explaining: Expository writing helps readers grasp complex subjects by breaking them down into simpler terms. It aims to clarify abstract concepts, processes, or phenomena, making them more accessible and understandable.
• Instructing: Expository writing provides step-by-step instructions or guidelines on how to perform a task, accomplish a goal, or understand a process. It offers a clear sequence of actions or explanations to ensure readers can follow and replicate the instructions.
• Presenting an analysis: Expository writing often involves analyzing and evaluating information, data, or evidence related to a particular subject. It may include comparing and contrasting different viewpoints, examining cause-and-effect relationships, or offering an objective evaluation of a situation.

Overall, the purpose of expository writing is to provide readers with accurate, unbiased, and well-organized information about a specific topic. It aims to enhance understanding, broaden knowledge, and facilitate learning by presenting information in a clear, coherent, and logical manner.

An expository essay is a good choice when the goal is to inform, explain, describe, or instruct. You may be assigned an expository essay as part of an in-class exam or coursework assignment. Here are some common situations in which writing an expository essay would be appropriate:

• Academic Assignments: Expository essays are frequently assigned in educational settings. Teachers often use this type of essay to assess students’ understanding of a particular subject or to teach them how to research and present information effectively. They are common in subjects such as English, history, science, social studies, or any discipline that requires a clear explanation or analysis of a topic.
• Instructional or How-to Writing: When you want to provide step-by-step instructions or guidance on how to perform a task, solve a problem, or achieve a specific outcome, an expository essay can be an appropriate format. This type of writing is commonly used in manuals, guidebooks, tutorials, or any instructional material.
• Journalism or News Writing: Expository writing is prevalent in journalism, where the goal is to inform readers about current events, news stories, or investigative reports. Journalists strive to present objective information, provide background details, and explain complex issues clearly to their audience.
• Professional or Technical Writing: In various professional fields, such as business, healthcare, engineering, or law, expository writing is utilized to convey information to colleagues, clients, or the general public. This includes writing reports, memos, manuals, research papers, or any form of communication that requires clear and factual presentation of information.

Expository essays can serve different purposes and present information in various ways. Here are five common types of expository essays:

• Descriptive essay: This type of expository essay focuses on describing a person, place, object, event, or any subject in detail. It aims to create a vivid and sensory-rich portrayal of the topic, using language that appeals to the reader’s senses and emotions.
• Process essay: Also known as a “how-to” essay, a process essay explains a sequence of steps or procedures to accomplish a task or achieve a particular outcome. It provides clear instructions and guidance, breaking down complex processes into manageable and easy-to-follow stages.
• Compare-and-contrast essay: This type of expository essay explores the similarities and differences between two or more subjects. It involves examining various aspects, characteristics, or elements of the subjects and highlighting their similarities, differences, or both.
• Cause-and-effect essay: A cause-and-effect essay explores the reasons (causes) behind an event, situation, or phenomenon, as well as the consequences (effects) that result from it. It aims to analyze and explain the relationship between causes and effects, demonstrating how one factor leads to another.
• Problem-and-solution essay: In this type of expository essay, a specific problem or issue is identified and analyzed, followed by the presentation of potential solutions or strategies to address it. The essay outlines the problem, examines its causes and effects, and proposes practical solutions or recommendations.

It’s important to note that these are not the only types of expository essays, and there can be variations or combinations of these types. Additionally, within each type, the specific approach and structure can vary depending on the requirements of the assignment or the writer’s purpose.

Structuring an expository essay involves organizing your thoughts, ideas, and information in a clear and logical manner. Here is a commonly used structure for an expository essay:

• Begin with an attention-grabbing hook to engage the reader.
• Provide some background information on the topic to set the context.
• Present a clear and concise thesis statement that states the main idea or purpose of the essay.
• Start each paragraph with a clear topic sentence that introduces the main point of the paragraph.
• Support your topic sentence with evidence, facts, examples, or expert opinions that relate to the main point.
• Provide detailed explanations, analysis, or descriptions to clarify and develop your ideas.
• Use transitional words and phrases to ensure smooth flow and coherence between paragraphs and ideas.
• Each paragraph should focus on a specific aspect or subtopic related to the main idea.
• Restate the thesis statement but rephrase it in a way that reinforces the main idea.
• Summarize the main points discussed in the body paragraphs.
• Avoid introducing new information or ideas in the conclusion.
• End with a closing statement that leaves a lasting impression.

Animal Testing in the Cosmetic Industry

Introduction.

Recent pictures in the news of caged animals with metal prongs holding their eyes open to test for chemicals have burned themselves into our memories. These painful tests have been supported by the cosmetic industry in the name of science for the past 40 years. The main question in 2009 is whether or not animals testing is still necessary? While most animal rights activists will say absolutely not, many scientists who are constantly searching for chemicals in product that cause cancers in humans still say yes. My main questions are what alternatives are there to this testing and what can be done?

(Paragraph 1) First, while some scientists say that deodorants or talcum powder cause breast or ovarian cancer, others say that more research has to be done (1), (2). Second, no matter how you look at it, we as consumers are being caught in the middle. Most of us use cosmetics in one form or other and we still need to feel safe. But is it right to inflict so much pain on innocent animals? Those poor animals should not need to suffer and die just to protect humans from harm and discomfort. What we must focus on, then, are the alternatives to animal testing. (Paragraph 2) What are the alternatives? The alternatives to animal testing that seem most logical would be those which replace animals in specific tests, therefore reducing the number of animals used. Another alternative is to make the tests better to lessen the animals’ suffering (3). A third alternative is to use human tissue or human skin cells and avoid using animals altogether. Hopefully, these alternatives will mark a new trend in the decline of animal testing in the future. (Paragraph 3) What can be done? Personally, I feel that violent methods used by extreme animal rights groups is not the answer. Burning down laboratories where caged animals are tested on or where humans lose their lives are only short term and inhuman. Setting animals free may cause them even more pain and suffering. Wouldn’t it be better to find ways where we as consumers can make a difference by refusing to buy animal tested products? In my opinion this would directly affect the cosmetic industry and force them to take action. Proof that some large scale action can be effective was when the EU issued the EU Cosmetic Directive, which on March 11, 2009, banned both animal testing and the marketing of animal tested products (4).

In conclusion, based on the new alternatives that test for harmful chemicals and the new initiatives made by the EU to ban the buying and selling of animal tested cosmetics, we can only hope that it will no longer be necessary to use animals in testing at all. As for us consumers, it is up to us to check that the products we use have not been tested on animals. Not only will we feel safe, but we will no longer have to feel guilty for making animals suffer when we buy cosmetic products.

Chapter 3: Paragraph Structure

3.3 Expository Paragraphs

Learning Objectives

• Provide evidence that supports a thesis, including relevant information on varying perspectives.
• Articulate concepts and information correctly and concisely.
• Decide the significance and merit of different facts, concepts and data.
• Organize an expository paragraph.

The main aim of an expository paragraph is to provide an effective explanation of a topic. While a descriptive paragraph strives to describe a subject and a narrative paragraph seeks to show personal growth, an expository paragraph tries to explain a topic or situation. Thus, expository paragraphs are written as if the writer is explaining or clarifying a topic to the reader. Since an expository paragraph is trying to clarify a topic, it is important that its sentences provide the categories or reasons that support the clarification of the topic. Moreover, these categories and reasons also provide the framework for the organization of the paragraph.

Much like the categories are essential to clarifying the topic, organization is the key to any well-developed paragraph. When composing your paragraph, think of its organization as a house, with each major part of a house representing a component of a paragraph. Just as the foundation provides support on which a house can be built, a thesis represents the foundation upon which to build a paragraph. The introductory sentence then functions as both the door and the framework for an expository paragraph. Like a house door, the introductory sentence must allow the reader to enter the paragraph. Additionally, just as walls are built upon the framework of a house, the body sentences of a paragraph are organized around the framework or the organizational scheme that is presented in the introductory sentence. The body sentences, much like the walls of a house, must be firm, strong and complete. Finally, a paragraph must include a concluding sentence that tops off the paragraph, much like a roof completes a house. As the roof cements the structure of the house and helps hold the walls in place, the concluding sentence must sum up the point of your body sentences and complete the paragraph.

Although the overall organization of an expository paragraph is important, you must also understand the organization of each component (the introductory, body, and concluding sentences) of your paragraph. The sections below identify the essential parts of each component of your paragraph, explaining the necessary information for each type of sentence.

While the guidelines listed below may feel constrictive, they are merely meant to guide you as a writer. Ultimately, the guidelines should help you write more effectively. The more familiar you become with how to organize a paragraph, the more energy you can focus on your ideas and your writing. As a result, your writing will improve as your ability to organize your ideas improves. Plus, focusing your energy on your argument and ideas rather than the organization makes your job as a writer more exciting and fun.

Introductory Sentences

A strong introductory sentence is crucial to the development of an effective expository paragraph. Unlike a persuasive paragraph, which takes a stand or forms an opinion about a subject, an expository paragraph is used when the writer wishes to explain or clarify a topic to the reader. In order to properly explain a topic, an expository paragraph breaks it into parts, explains each component in relation to the whole, and uses each component to justify the explanation of the topic. Thus, when writing an introductory sentence, it is crucial to include the explanation or clarification of the topic and the categories or components used to produce this explanation.

Introductory sentences

• Introduce the issue.
• Present the topic and its explanation or clarification.
• Provide the categories used to explain the topic.
• Provide the thesis statement.

Since the success of the paragraph rests on the introductory sentence, it is important to understand its essential components. Usually, when expository paragraphs fail to provide a clear explanation, it is not because the writer lacks explanations or clarifications, but rather because the explanations are not properly organized and identified in the introductory sentence. One of the most important jobs of an introductory sentence is that it introduces the topic or issue. Most explanations cannot be clarified without at least some background information. Thus, it is essential to provide a foundation for your topic before you begin explaining. For instance, if you wanted to explain what happened at the first Olympic Games, your introductory sentence would first need to briefly mention how the first games happened. In doing so, you ensure that your audience is as informed about your topic as you are, and thus, you make it easier for your audience to understand your explanation.

Below, the main jobs of the introductory sentence are described and explained in detail.

The purposes of introductory sentences

Introductory sentences introduce the topic and suggest why it is important.

Example : An analysis of the essay exam results of the new English class shows that the new class format promotes close reading and better essay organization.

This sentence tells the reader both that the topic of the paper will be the benefits of the new English class and that the significance of these benefits is the improvement of close reading and essay organization.

Introductory sentences outline the structure of the paragraph and highlight the main ideas.

Example : Considering the results of the high school exit exam, it is apparent that the school curriculum is not properly addressing basic math skills, such as fractions, percentages and long division.

This sentence indicates the main ideas (fractions, percentages and long division) of the paragraph and indicates the order in which they will be presented in the body sentences.

Introductory sentences state the thesis.

Example : University and college work experience programs will require all students to take a résumé and cover letter writing workshop in order to better prepare them for employment.

This thesis statement indicates the explanation of the paragraph.

In addition to introducing the topic of your paragraph, your introductory sentence also needs to introduce each of the points you will cover in your body sentences. By providing your audience with an idea of the points you will make in your paragraph, your introductory sentence serves as a guide map, not only for your audience, but also for you. Including your main points in your introductory sentence not only allows your audience to understand where your paragraph is headed, but also helps you as a writer remember how you want to organize your paragraph. This is especially helpful if you are not writing your paragraph in one sitting, as it allows you to leave and return to your paragraph without forgetting all of the important points you wanted to make.

Most importantly, when writing an introductory sentence, it is essential to remember that you must capture the interest of your reader. Thus, it is your job as the writer to make the introduction entertaining or intriguing. In order to do so, consider using a quotation, a surprising or interesting fact, an anecdote, or a humorous story. While the quotation, story, or fact you include must be relevant to your paragraph, placing one of these at the beginning of your introduction helps you not only capture the attention of the reader, but also introduce your topic and argument, making your introduction interesting to your audience and useful for your argument and paragraph.

Body Sentences

In an expository paragraph, the body sentences are where the writer has the opportunity to explain or clarify their viewpoint. By the concluding sentence, the writer should adequately clarify the topic for the reader. Regardless of a strong thesis statement that properly indicates the major subtopics of the paragraph, paragraphs with weak body sentences fail to properly explain the topic and indicate why it is important. Body sentences of an expository paragraph are weak when no examples are used to help illuminate the topic being discussed or when they are poorly organized. Occasionally, body sentences are also weak because the quotes used complicate rather than simplify the explanation. Thus, it is essential to use appropriate support and to adequately explain your support within your body sentences.

In order to create a body sentence that is properly supported and explained, it is important to understand the components that make up a strong body sentence. The bullet points below indicate the essential components of a well-written, well-argued body sentence.

Body sentences

• Begin by reflecting the argument of the thesis statement.
• Support the argument with useful and informative quotes from sources such as books, journal articles, expert opinions, etc.
• Briefly explain each quote and indicate its significance.
• Ensure that the information provided is relevant to the thesis statement.
• Transition into the next body sentence.

Just as your introduction must introduce the topic of your paragraph, the first body sentence must introduce the main subpoint for that sentence. For instance, if you were writing a body sentence for a paragraph explaining the factors that led to Canadian conscription in World War II, one body sentence could discuss the impact of Canada’s relationship with Britain on the decision to conscript Canadian men. To do so, you would begin by explaining why Canada felt obliged to come to Britain’s aid. Your audience now knows what the paragraph is explaining, and you can also keep track of your ideas.

Following the topic sentence, you must provide some sort of fact that supports your claim. In the example of the World War II paragraph, maybe you would provide a quote from a historian. After your quote or fact, you must always explain what the quote or fact is saying, stressing what you believe is most important about your fact. It is important to remember that your audience may read a quote and decide it is indicating something entirely different than what you think it is explaining. Or, maybe some of your readers think another aspect of your quote is important. If you do not explain the quote and indicate what portion of it is relevant to your clarification, then your reader may become confused or may be unconvinced by your explanation. Consider the possible interpretations for the statement below.

Example : While Canada’s involvement in World War II did not lead to as many young men dying as in Britain, a generation was still deeply affected.

Interestingly, this statement seems to be saying two things at once: that Canada’s young men were not killed in the same numbers as those of other Allied countries, and that the number of deaths nonetheless marked a generation. On the one hand, the historian seems to say that the two outcomes are not directly linked. On the other hand, the historian also indicates that the two outcomes are linked in that the deaths caused Canada to be impacted by the war. Because of the tension in this quotation, if you used it for your World War II paragraph, you would need to explain that the significant portion of the quote is the assertion that links the outcomes.

In addition to explaining what this quote is saying, you would also need to indicate why this is important to your explanation. When trying to indicate the significance of a fact, it is essential to try to answer the “so what.” Imagine you have just finished explaining your quote to someone and they have asked you “so what?” The person does not understand why you have explained this quote, not because you have not explained the quote well, but because you have not told them why they need to know what the quote means. This—the answer to the “so what”—is the significance of your paragraph and is essentially your clarification within the body sentences.

Concluding Sentences

The concluding sentence of an expository paragraph is an author’s last chance to create a good impression. Hence, it is important to restate the thesis statement at the beginning of the sentence in order to remind the reader of your topic and explanation. Since it is at the end of the paragraph, the concluding sentence also should add a sense of closure and finality to the clarification of the paragraph. It is important to re-emphasize the main idea without being repetitive or introducing an entirely new idea or subtopic. While your concluding sentence can suggest further research or investigation, do not make this question the focus of the sentence. Thus, you should briefly and concisely reiterate the strongest clarifications of the paragraph, reminding the reader of the validity of your thesis or explanation and bringing closure to your paragraph.

The following is an example of a paragraph that describes why graduating from college is harder than graduating from high school. The paragraph has been broken up to describe the purpose of each sentence (or group of sentences).

Concluding sentences

• Briefly summarize the main points of the paragraph.
• Provide a strong and effective close for the paragraph.

You may feel that the concluding sentence is redundant or unnecessary. However, do not forget that this is your last chance to explain the significance of your argument to your audience. Just as your body sentences strive to present the significance of each fact or quote you use, your concluding sentence should sum up the significance of your argument. Thus, you should consider making a bold statement in your concluding sentence by evoking a vivid image, suggesting results or consequences related to your argument, or ending with a warning. Through using these strategies, you not only make your concluding sentence more exciting, but you also make your paragraph and your argument more important.

Points to Consider

• Write an expository paragraph about your favourite movie or book, paying special attention to why a certain book or movie is your favourite. Be sure to briefly but adequately summarize the movie or book in order to provide a concise and comprehensible explanation. Additionally, be sure to use concrete details and examples to explain why you enjoy the book or movie you are writing about. Simply summarizing the plot will not explain to the reader why the book or movie is entertaining to you.
• Write an expository paragraph about a historical event, indicating at least three factors that contributed to its development. For instance, you could discuss how factors such as residential schools led to the reconciliation movement. A factor could be an event, an individual, or a movement that is historically significant. In order to properly show how certain factors caused or contributed to a specific event, you must clarify both the factors and the event itself.

An expository essay attempts to explain a topic in-depth, demonstrating expert knowledge and understanding.

This form of essay is structured around the clear, factual presentation of information, devoid of the writer’s personal opinions or arguments.

The primary goal is to inform or explain rather than persuade.

Unlike an argumentative essay, which is built around defending a particular point of view with evidence and persuasion, an expository essay maintains a neutral stance, focusing on delivering straightforward facts and explanations.

An example of expository writing could be an article explaining the process of photosynthesis.

The article would systematically describe each stage of how plants convert sunlight into energy, detailing the role of sunlight, water, and carbon dioxide.

It would explain the sequence of reactions – first, second, third, fourth, fifth – that occur and the importance of each step in supporting the life of the plant.

An expository essay generally follows this essay format:

• A) To persuade the reader to adopt a particular viewpoint

• A) An expository essay uses creative storytelling techniques

Differences Between Expository and Argumentative Essays

Expository and argumentative essays are both common writing styles in academic and professional contexts, but they serve different purposes and follow different structures.

Here are the key differences between them:

• Expository Essay : The primary purpose is to explain, describe, or inform about a topic. It focuses on clarifying a subject or process, providing understanding and insight.
• Argumentative Essay : The goal is to persuade the reader to accept a particular point of view or to take a specific action. It’s about presenting a stance and supporting it with evidence and logic.
• Expository Essay : It maintains a neutral and objective tone. The writer presents information factually and impartially, without expressing personal opinions or biases.
• Argumentative Essay : It often adopts a more assertive, persuasive, and subjective tone. The writer takes a clear position and argues in favor of it, using persuasive language.
• Expository Essay : The reader is expected to gain knowledge, understand a process, or become informed about a topic. There’s no expectation for the reader to agree or disagree.
• Argumentative Essay : The reader is encouraged to consider the writer’s viewpoint, evaluate arguments, and possibly be persuaded to adopt a new perspective or take action.
