English [ edit ]

Etymology [ edit ].

From Late Middle English thesis ( “ lowering of the voice ” ) [1] and also borrowed directly from its etymon Latin thesis ( “ proposition, thesis; lowering of the voice ” ) , from Ancient Greek θέσῐς ( thésis , “ arrangement, placement, setting; conclusion, position, thesis; lowering of the voice ” ) , from τῐ́θημῐ ( títhēmi , “ to place, put, set; to put down in writing; to consider as, regard ” ) [2] [3] (ultimately from Proto-Indo-European *dʰeh₁- ( “ to do; to place, put ” ) ) + -σῐς ( -sis , suffix forming abstract nouns or nouns of action, process, or result ) . The English word is a doublet of deed .

Sense 1.1 (“proposition or statement supported by arguments”) is adopted from antithesis . [2] Sense 1.4 (“initial stage of reasoning”) was first used by the German philosopher Johann Gottlieb Fichte (1762–1814), and later applied to the dialectical method of his countryman, the philosopher Georg Wilhelm Friedrich Hegel (1770–1831).

The plural form theses is borrowed from Latin thesēs , from Ancient Greek θέσεις ( théseis ) .

Word of the Day

What it means.

Symposium can refer either to a formal meeting at which experts discuss a particular topic, or to a collection of articles on a particular subject. Symposium has two plural forms: symposia and symposiums .

// Professors and graduate students attended a three-day symposium on climate change.

// The organization will be publishing a symposium on genetic research.

symposium in Context

“In 1966, at a meeting remembered in anthropological lore as the beginning of hunter-gatherer studies, seventy-five experts assembled in Chicago to synthesize our knowledge about foraging peoples. More than ninety-nine per cent of human history was spent without agriculture, the organizers figured, so it was worth documenting that way of life before it disappeared altogether. The symposium —and an associated volume that appeared two years later, both titled ‘Man the Hunter’—exemplified an obsession with hunting, meat-eating, and maleness.” — Manvir Singh, The New Yorker , 25 Sept. 2023

Did You Know?

When you hear the word symposium , you may—quite understandably—envision conferences full of intellectuals giving heady presentations on various arcana . But it was drinking, more than thinking, that drew people to the original symposia and gave us the word. Symposium ( symposia or symposiums in plural form) comes from the Greek noun symposion , the word ancient Greeks used for a drinking party that follows a banquet. Symposion in turn comes from sympinein , a verb that combines pinein , meaning “to drink,” with the prefix syn -, meaning “together.” Originally, English speakers only used symposium to refer to such an ancient Greek party, but in the 18th century British gentlemen’s clubs started using the word for confabs in which conversation was fueled by drinking. By the end of the 18th century, symposium had gained the more sober sense we know today, referring to meetings in which the focus is more on imbibing ideas and less on imbibing, say, mead .
