What is the language of the Navajo's called?
Navajo language
The Apachean languages, of which Navajo is one, are thought to have arrived in the American Southwest from the north by 1500 CE, probably passing through Alberta and Wyoming.[14][15] Archaeological finds considered to be proto-Navajo have been located in the far northern New Mexico around the La Plata, Animas and Pine rivers, dating to around 1500. In 1936, linguist Edward Sapir showed how the arrival of the Navajo people in the new arid climate among the corn agriculturalists of the Pueblo area was reflected in their language by tracing the changing meanings of words from Proto-Athabaskan to Navajo. For example, the word *dè:, which in Proto-Athabaskan meant "horn" and "dipper made from animal horn", in Navajo came to mean "gourd" or "dipper made from gourd". Likewise, the Proto-Athabaskan word *ɫ-yáxs "snow lies on the ground" in Navajo became sàs "corn lies on the ground". Similarly, the Navajo word for "corn" is nà:-dą:, derived from two Proto-Athabaskan roots meaning "enemy" and "food", suggesting that the Navajo originally considered corn to be "food of the enemy" when they first arrived among the Pueblo people.[16][17]
