Okanagan, or Colville-Okanagan, or Nsyilxcən (n̓səl̓xcin̓), is a Salish language which arose among the indigenous peoples of the southern Interior Plateau region based primarily in the Okanagan River Basin and the Columbia River Basin in precolonial times in Canada and the United States. Following British, American, and Canadian colonization during the 1800s and the subsequent assimilation of all Salishan tribes, the use of Colville-Okanagan declined drastically.
