This dissertation is the first grammatical sketch of the Nxa’amxcin (Moses-
Columbian) language. Nxa’amxcin is an endangered member of the Southern Interior branch of the Salish language family, a linguistic group indigenous to the
Pacific Northwest region of North America. Building on previous work by other
Salish linguists, I address to varying degrees all three major aspects of the
grammar (phonology, syntax and morphology) from a Lexeme-Morpheme Base
Morphology approach to word formation (Beard 1995).
