Tahltan is a critically endangered language. Several linguists classify Tahltan as a dialect of the same language as Tagish and Kaska. Tahltan belongs to the Athabaskan-Eyak-Tlingit language family. Edward Sapir originally constructed the term Na-Dene to refer to a combined family of Athabaskan, Tlingit, and Haida (the existence of the Eyak language was not known to him at the time). However, Haida is now generally considered a language isolate. tht tht THT false THT 1950-05-09 THT
