English-Corpora.org Corpora at this site were created by Mark Davies, Professor of Linguistics at Brigham Young University. The corpora have many different uses, including: finding out how native speakers actually speak and write; finding the frequency of words, phrases, and collocates; looking at language variation and change, e.g. historical, dialects, and genres; gaining insight into culture, e.g what is said about different concepts over time and in different countries; designing authentic language teaching materials and resources.
