"The Upper Kuskokwim language (also called Kolchan or Goltsan or Dinak'i) is an Athabaskan language of the Na-Den\u00E9 language family. It is spoken by the Upper Kuskokwim people in the Upper Kuskokwim River villages of Nikolai, Telida, and McGrath, Alaska. About 40 of a total of 160 Upper Kuskokwim people (Dichinanek\u2019 Hwt\u2019ana) still speak the language. A practical orthography of the language was established by Raymond Collins, who in 1964 began linguistic work at Nikolai."@en . "Dinak\u02BCi"@en . . "Upper Kuskokwim"@en . "kuu" . . . . .
