The corpora at this site were created by Mark Davies, Professor of Linguistics at Brigham Young University. They are used by more than 200,000 people each month (more than 370,000 visits) -- for example, 65,000 distinct people each month for COCA alone. This makes them perhaps the most widely-used corpora currently available.

  • finding out how native speakers actually speak and write

  • finding the frequency of words, phrases, and collocates
