Usage

What does corpus mean? Corpus most commonly refers to a large or comprehensive collection of creative works, such as all of the writings of a particular author. An artist’s corpus is their body of work, and in fact the word corpus comes from the Latin word meaning “body.” (This Latin word appears in the well-known legal phrase habeas corpus, meaning “(you may) have the body.”)More generally, corpus is used in English to refer to the main body, section, or substance of something. The word is used in a more specific way in linguistics to refer to an entire set of a particular linguistic element within a language, such as words or sentences. It’s also used in several more specific ways in the context of anatomy in the names of body parts. The correct plural of corpus can be either corpora or corpuses. (Other Latin-derived words can be pluralized in the same way as corpora.)Example: Instead of devoting my dissertation to examining a specific theme throughout her corpus, I decided to focus on a single work.

Etymology

Origin of corpus

First recorded in 1225–75; Middle English, from Latin

---

Explanation

A corpus is a collection of writings. If you tend to never throw anything away, you might have your entire school corpus, from your first scribbled words to your high school English essays. The written works of an author, or from one specific time period, can be called a corpus if they're gathered together into a collection or talked about as a group. You could discuss the corpus of Dr. Seuss, for example. Corpus sounds a little like corpse, and that's no coincidence; corpus means "body" in Latin, and though it's come to mean specifically "body of work," the two words are closely related.
