Ket language
Ket, formerly known as
Yenisei Ostyak, is a Siberian
language isolate, apparently unrelated to any other language in the world (other than Yugh, a recently-extinct language that was clearly related to Ket). It is spoken by about 2,000 people along the middle
Yenisei Basin. Attempts have been made by
Soviet scholars to establish a relationship with either
Burushaski or the
Sino-Tibetan languages.
