Timbisha language
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 is monolingual, and all use English regularly in their daily lives. Until the late 20th century, the people called themselves and their language "Shoshone." The tribe then achieved federal recognition under the name Death Valley Timbisha Shoshone Band of California. This is an Anglicized spelling of the native name of Death Valley, tümpisa, pronounced , which means "rock paint" and refers to the rich sources of red ochre in the valley. Timbisha is also the language of the so-called "Shoshone" groups at Bishop, Big Pine, Darwin, Independence, and Lone Pine communities in California and the Beatty community in Nevada. It was also the language spoken at the former Indian Ranch reservation in Panamint Valley. Classification
Timbisha is one of the Central Numic languages of the Numic branch of Uto-Aztecan. It is most closely related to Shoshoni and Comanche. Geographic distribution
Timbisha was formerly spoken in the region between the Sierra Nevada mountains of eastern California and the region just to the east of Death Valley in Nevada. Principal valleys where villages were located were (from west to east) Owens Valley, Indian Wells Valley, Saline Valley, Panamint Valley, and Death Valley. In addition, there were villages along the southern slopes of the Kawich Range in Nevada. Dialects
Each valley had its own variety of Timbisha with mostly lexical differences between them. There was, however, a general loss of  as one moved west across Timbisha territory with  virtually gone in Owens Valley varieties. McLaughlin's grammar is based on the far eastern variety from Beatty, Nevada, while Dayley's is based on a central variety from Death Valley. Phonology

Timbisha spelling is based on Dayley and uses the Roman alphabet. Ü is used for  and ng for . Grammar
Study of Timbisha has been carried on by Jon Dayley and John McLaughlin, both of whom wrote grammatical descriptions. Dayley has published a dictionary. Word order and case marking
Timbisha word order is usually SOV as in:

The accusative case and possessive case are marked with suffixes. Adverbial relationships are marked with postpositions on nouns as well as with true adverbs. For example:

Adjectives are usually prefixed to the nouns they modify, unless the relationship is temporary when they are independent words with special suffixes. Compare tosa-kapayu, 'white-horse', "palomino or other pale-colored breed" and tosapihtü kapayu, 'white/pale horse', "white or pale horse" (who happens to be white or pale, but whose siblings may be any color).

Some common intransitive verbs have suppletive forms for singular or plural subjects and some common transitive verbs have suppletive forms for singular or plural objects.
