What does corpus mean?
A corpus is a systematically gathered body of material — most often a large collection of texts or speech recordings assembled so that language can be studied statistically. In modern usage the word belongs chiefly to linguistics and data science: researchers build corpora to track how words change meaning over time, how grammar varies across communities, or how machines learn to read and translate. Beyond that technical sense, corpus also serves as a respectful shorthand for the entire output of a writer, composer, or thinker — one speaks of Shakespeare's corpus or a philosopher's complete corpus. The word comes directly from Latin, where it meant simply "body," and that physical metaphor still colors its tone: a corpus feels substantial, organized, and whole. Formal rather than conversational, it signals rigor and comprehensiveness, making it a precise and useful alternative to vaguer words like "collection" when the emphasis falls on systematic completeness.
nounA collection of written or spoken texts, especially one assembled for linguistic research; more broadly, the complete body of work produced by a particular writer or on a particular subject.
- A large, structured collection of texts or transcripts compiled for linguistic study.
- The complete body of writings or works by a particular author, or on a particular subject.
"The linguists built a corpus of a million words drawn from everyday conversation."
"Researchers mined the corpus for patterns in how teenagers use slang."
"Her complete corpus spans five decades and includes over two hundred poems."
Academic writing strongly favors the Latin plural "corpora"; the anglicized "corpuses" appears occasionally but is less formal.
"The department maintains several parallel corpora for translation research."
Every time you say 'corporation,' you're using the same Latin root as 'corpus' — ancient Romans literally thought of legal bodies as 'bodies' of people.

Etymology of corpus
Corpus was borrowed directly from Latin, where it meant "body" — the physical body of a person or animal. English adopted it in scholarly contexts, preserving the Latin sense of a unified whole made up of parts. The same root produced many familiar English relatives, including "corpse" (a dead body), "corporeal" (bodily), "corps" (a military body), and ultimately "corporate" and "corporation," which treat organizations as legal "bodies." The specialized sense of a collection of texts developed as scholars began treating bodies of writing as objects of systematic study, a usage now central to corpus linguistics.

How corpus is actually used
"Corpus" is a formal, scholarly term most at home in linguistics, law, and literary criticism; it sounds out of place in casual conversation. The plural "corpora" is standard in academic writing, though "corpuses" also appears.
Easily confused with corpus
