The Tsimshianic languages are a family of languages spoken in northwestern British Columbia and in southern Alaska on Annette Island and Ketchikan. About 2,170 people of the ethnic Tsimshian English pronunciation: /ˈsɪmʃiən/ population in Canada still speak the Tsimshian languages; about 50 of the 1,300 Tsimshian people living in Alaska still speak Coast Tsimshian. Tsimshianic languages are considered by most linguists to be an isolate group of languages, with four main languages or lects: Coast Tsimshian, Southern Tsimshian, Nisga’a, and Gitksan.
The Tsimshianic languages were included by Edward Sapir in his Penutian hypothesis, a theory which is currently not widely accepted but is undergoing investigation by Marie-Lucie Tarpent.
Coast Tsimshian is spoken along the lower Skeena River in Northwestern British Columbia, on some neighbouring islands, and to the north at New Metlakatla, Alaska. Southern Tsimshian is spoken on an island quite far south of the Skeena River in the village of Klemtu. Southern Tsimshian is severely endangered, nearing extinction. Nisga’a is spoken along the Nass River. Gitksan is spoken along the Upper Skeena River around Hazelton and other areas.
Nisga’a and Gitksan are very closely related and are usually considered dialects of the same language by linguists. However, speakers from both groups consider themselves ethnically separate from each other and from the Tsimshian and thus consider Nisga’a and Gitksan to be separate languages. Coast and Southern Tsimshian are also often regarded as dialects of the same language.
