Mosan languages

Hypothetical language family including Salishan, Wakashan, and Chimakuan

Mosan is a hypothetical language family consisting of the Salishan, Wakashan, and Chimakuan languages of the Pacific Northwest region of North America. It was proposed by Edward Sapir in 1929 in the Encyclopædia Britannica. Little evidence has been adduced in favor of such a grouping, no progress has been made in reconstructing it, and it is now thought to reflect a language area rather than a genetic relationship. The term persists outside academic linguistic literature because of Sapir's stature.
