The grammar of the St. Lawrence Island/Siberian Yupik Eskimo language was written for college-level classes containing a mixture of Yupik speakers and non-speakers, and for students learning the language on their own. It uses only the Central Siberian Yupik dialect spoken on St. Lawrence Island (Alaska) and on a small portion of the Asian mainland. The first chapter gives an overview of Yupik phonology, spelling, and syllabification. Subsequent chapters address specific form classes and grammatical constructions in detail. Exercises are included with each chapter. Appendixes contain charts of noun case endings, verb mood endings, and personal pronouns, and a summary of the ways in which base-final /te/ is affected by suffixes. (MSE)
