Creek (or Muskogee) is a Muskogean language spoken by several thousand members of the Muscogee (Creek) and Seminole nations of Oklahoma and by several hundred members of the Seminole Tribe of Florida. This volume is the first modern grammar of Creek, compiled by a leading authority on the languages of the southern United States. Intended for scholars, students, and Creek instructors, this reference grammar describes all the major morphological and syntactic patterns in the language. Special attention is given to pitch accent and tone, active agreement, locative prefixes, tense, aspect, and switch reference. The description covers several hundred years of documentation and draws heavily on materials written by Creek speakers. It is likely to be the definitive source on the language for years to come.
