A corpus is a large collected body of writing or of data. A corpus of texts, the corpus of his work, a language corpus.
In linguistics it is a searchable collection of real language used to find out how words are actually used rather than how anybody thinks they are, and dictionaries have been built on them since the 1980s. The plural is corpora.
