Definition
Mosan refers to a hypothetical language family once proposed to link several language families of the Pacific Northwest. This idea suggests these diverse languages share a common ancestor. It's like suggesting different breeds of dogs all came from a single wolf ancestor. The Mosan hypothesis included languages like Salishan, Wakashan, and Chimakuan. While intriguing, this theory is now largely rejected by linguists. Most evidence suggests these language families developed independently. Therefore, the term 'Mosan' is mostly of historical interest in linguistics.
