The Corpus of Contemporary American English
The Corpus of Contemporary American English (COCA) is a large and balanced corpus of American English. It contains more than one billion words of text (25+ million words each year from 1990 to 2019) from eight genres: spoken, fiction, popular magazines, newspapers, academic texts, TV and Movie subtitles, blogs, and other web pages. COCA is probably the most widely-used corpus of English and it offers unparalleled insight into variation in English.
