Shoshone or Shonshoni is an Uto-Aztecan language spoken in Nevada, Utah, Idaho, Montana and Wyoming in the USA by about 3,000 people, a few hundred of whom speak the language fluently. The main dialects of Shoshone include Western Shoshone, which is spoken in Nevada, Gosiute in western Utah, Northern Shoshone in southern Idaho and northern Utah, and Eastern Shoshone in Wyoming.
The majority of Shoshone speakers are elderly, however there are a number of efforts to revive and revitalise the language among younger Shoshone people. The University of Utah, for example, is running the Shoshone Youth Language Apprenticeship Program.
The two main spelling systems for Shoshone are known as Crum-Miller, which was developed in the 1970s, and the Idaho State University system, which was developed in the early 21st century.
