Tsetsaut languageとは 意味・読み方・使い方

Tsetsaut is an extinct Athabascan language formerly spoken in the Portland Canal area of northwestern British Columbia. Virtually everything known of the language comes from the limited material recorded by Franz Boas in 1894 from two Tsetsaut slaves of the Nisga'a, which is enough to establish that Tsetsaut formed its own branch of Athabaskan. It is not known precisely when the language became extinct. One speaker was still alive in 1927. The Nisga'a name for the Tsetsaut people is "Jits'aawit"
