What is another word for na-dene?
Pronunciation: [nˈɑːdˈiːn] (IPA) 
Na-Dene is a language family spoken by indigenous people in Alaska, western Canada, and the southwestern United States. Some synonyms for Na-Dene include Athabaskan, Eyak-Athabascan, and Dene-Yeniseian. The term Athabaskan is derived from the Cree word for "grass," which refers to the habitat of the people who speak this language. Eyak-Athabascan includes the Eyak language, which is extinct, and the Athabaskan languages. The Dene-Yeniseian hypothesis suggests that Na-Dene and the Yeniseian language family spoken in Siberia are related, although this is a controversial theory. Despite the varied terminology, all of these terms refer to a group of indigenous languages with a rich history and ongoing significance in the North American region.
