Also known as Diné Bizaad, part of the the Apachean subgroup of the Athabaskan branch of the Na-Dené language family. Diné means “the people” or “children of the holy people,” and so the language is that of the people. The language is unique in its nasalization of some vowels, its use of glottal stops and releases, and its reliance on tone to signify meaning.
