Word Origin & History

chi
22nd letter of the Gk. alphabet, representing a -kh- sound; shaped like an X, it was used to signify such a shape or arrangement. Some dialects used chi to represent the -ks- sound properly belonging to xi; Latin picked this up and the sound value of chi in Latin-derived alphabets is now that of our
X.
