Timbisha (Tümpisa) or Panamint (also called Koso) is the language of the Native American people who have inhabited the region in and around Death Valley, California, and the southern Owens Valley since late prehistoric times.

There are a few elderly individuals who can speak the language in California and Nevada, but none are monolingual, and all use English regularly in their daily lives.

The tribe then achieved federal recognition under the name Death Valley Timbisha Shoshone Band of California.

There was, however, a general loss of h as one moved west across Timbisha territory with h virtually gone in Owens Valley varieties.

Study of Timbisha has been carried on by Jon Dayley and John McLaughlin, both of whom wrote grammatical descriptions.

For example: kahni-pa'ahouse-onkahni-pa'ahouse-on"on the house"Adjectives are usually prefixed to the nouns they modify, unless the relationship is temporary when they are independent words with special suffixes.
