The first complete descriptive grammar of Lillooet, an interior Salish language spoken in British Columbia (Canada), uses the structuralist method to provide a detailed analysis of the language's sound system, word structure, and syntax, and to explain their functions and positions within Lillooet's overall linguistic structure. The account is designed to be used by students and linguists. A fully translated Lillooet text is appended, to illustrate the grammatical patterns discussed in the book. A second appendix has a conversion table comparing the standard Amerindian orthography with the practical orthography used in Lillooet-speaking communities. Contains 79 references. (MSE)
