Ket

Ket is the last surviving member of the Yenisei family of
languages and is spoken by about 550 people along the Yenisei
River and its tributaries in Central Siberia.

Ket is also known as Yenisei-Ostiak and Ostyganna qa’ and
is related to Yugh or Yug, which died in the 1970s, and Pumpokol,
Arin and Kot, which became extinct during the 18th and 19th
centuries. These languages are thought by some linguists
to be related to the North-Caucasian and Sino-Tibetan languages;
and by others, such as Edward Vajda, a historical linguist at Western
Washington University, to the Na-Dene languages of North
America, although the tonal system of Ket is closest to
Vietnamese.
