The Muskogean family of languages has two main divisions, the Western and the Eastern. Among extant languages, the Western division is represented only by Choctaw-Chickasaw; the extant languages of the Eastern division may be further divided into three subgroups: (1) Alabama-Koasati, (2) Hitchiti-Mikasuki, and (3) Creek-Seminole. The material on which the present paper is based is taken from my field notes on Choctaw, Koasati, Hitchiti, and Creek (Muskogee). These four languages may be considered representative of the family as a whole, since both divisions and all the subgroups are represented among them.
