Moses-Columbia, or Columbia-Wenatchi (in Moses-Columbia: Nxaʔamxcín), is an extinct Southern Interior Salish language, also known as Nxaảmxcín. Speakers traditionally lived in the Colville Indian Reservation. The Columbia people were followers of Chief Moses. There were two dialects, Columbia (Sinkiuse, Columbian) and Wenatchi (Wenatchee, Entiat, Chelan). Wenatchi was the heritage language of the Wenatchi, Chelan, and Entiat tribes, Columbian of the Sinkiuse-Columbia. Pauline Stensgar, who died on May 2, 2023 at age 96, is reported to have been the last known fully fluent speaker.
