Comanche [SEP] Language
The language spoken by the Comanche people, "Comanche" ("Numu tekwapu"), is a Numic language of the Uto-Aztecan language group. It is closely related to the language of the Shoshone, from which the Comanche diverged around 1700. The two languages remain closely related, but a few low-level sound changes inhibit mutual intelligibility. The earliest records of Comanche from 1786 clearly show a dialect of Shoshone, but by the beginning of the 20th century, these sound changes had modified the way Comanche sounded in subtle, but profound, ways. Although efforts are now being made to ensure survival of the language, most of its speakers are elderly, and less than one percent of the Comanches can speak it.
