Oirat language

Oirat (Clear script: ᡆᡕᡅᠷᠠᡑ ᡘᡄᠯᡄᠨ, Oirad kelen, IPA: [œːrt cɛˈlən]; Kalmyk: Өөрд, Őrd; Khalkha Mongolian: Ойрад, Oirad) is a Mongolic language spoken by the descendants of Oirat Mongols, now forming parts of Mongols in China, Kalmyks in Russia and Mongolians. Largely mutually intelligible to other core Central Mongolic languages, scholars differ as to whether they regard Oirat as a distinct language or a major dialect of the Mongolian language. Oirat-speaking areas are scattered across the far west of Mongolia, the northwest of China and Russia's Caspian coast, where its major variety is Kalmyk. In China, it is spoken mainly in Xinjiang, but also among the Deed Mongol of Qinghai and Subei County in Gansu.

In all three countries, Oirat has become variously endangered or even obsolescent as a direct result of government actions or as a consequence of social and economic policies. Its most widespread tribal dialect, which is spoken in all of these nations, is Torgut. The term Oirat or more precisely, Written Oirat is sometimes also used to refer to the language of historical documents written in the Clear script.
