Plains Apache language

The Plains Apache language (or Kiowa Apache) is a Southern Athabaskan language spoken by the Plains Apache peoples living primarily in central Oklahoma.

Plains Apache is most closely related to other Southern Athabaskan languages like Navajo, Chiricahua Apache, Mescalero Apache, Lipan Apache, Western Apache, and Jicarilla Apache. Plains Apache is the most divergent member of the subfamily. The language is extremely endangered with perhaps only one or two native speaking elders. Alfred Chalepah, Jr., who might have been the last native speaker, died in 2008.
