Chemehuevi language

Colorado River Numic (also called Ute /ˈjuːt/, Southern Paiute /ˈpaɪjuːt/, Ute–Southern Paiute, or Ute-Chemehuevi /tʃɛmɪˈweɪvi/), of the Numic branch of the Uto-Aztecan language family, is a dialect chain that stretches from southeastern California to Colorado. Individual dialects are Chemehuevi, which is in danger of extinction, Southern Paiute (Moapa, Cedar City, Kaibab, and San Juan subdialects), and Ute (Central Utah, Northern, White Mesa, Southern subdialects). According to the Ethnologue, there were a little less than two thousand speakers of Colorado River Numic Language in 1990, or ca. 40% out of an ethnic population of 5,000.

The Southern Paiute dialect has played a significant role in linguistics, as the background for a famous article by linguist Edward Sapir and his collaborator Tony Tillohash on the nature of the phoneme.
