Crow, a Siouan language spoken on the Crow Reservation in southeastern Montana, remains one of the most vital Native American languages, with several thousand speakers. A Grammar of Crow is the first detailed description of the Crow language in a contemporary linguistic framework. Randolph Graczyk draws on more than thirty-five years of daily contact with speakers of the language and his training as a linguist to offer an in-depth description and analysis of the crucial elements of the language, illustrated with numerous examples. nbsp; The grammar is primarily descriptive, couched in terms of universal linguistic theory. It examines phonological, morphological, and syntactic features and treats the major phonological and morphological structures of Crow, paying considerable attention to the syntax of relative and subordinate clauses, noun incorporation, and various serial verb constructions. The switch reference system is also discussed in detail.
