The Navahos call themselves “diné” meaning, simply “men” or “people.” All tribes of the Athapaskan linguistic stock designate themselves by a form of this same word, such as “dane, dene, dune, dindje, nde, tinneh, tunne, teni,” etc. The languages spoken by this diversified and widely distributed group, i.e., the Athapaskans, are sufficiently similar in vocabulary, phonetics and morphology, to amply justify the belief that they are descended from a common parent stock. This linguistic family occupies a tremendous sweep of territory from the northern interior of Alaska to Sonora and Chihuahua, more than 4000 miles from north to south.
