Altay language

Gorno-Altai (also Gorno-Altay) is a Turkic language, spoken officially in the Altai Republic, Russia. The language was called Oyrot prior to 1948.

Due to its isolated position in the Altai Mountains and contact with surrounding languages, the classification of Altai within the Turkic languages has often been disputed. Because of its geographic proximity to the Shor and Khakas languages, some classifications place it in a Northern Turkic subgroup. Due to certain similarities with Kyrgyz, it has been grouped with the Kypchak languages. A more recent classification by Talat Tekin places Southern Altai in its own subgroup within Turkic and groups the Northern Altai dialects with Lower Chulym and the Kondoma dialect of Shor.

Altai is spoken primarily in the Altai Republic (Southern Altai) and Altai Krai (Northern Altai).

Alongside Russian, Altai is an official language of the Altai Republic. The official language is based on the Southern dialect spoken by the group called the Altay-Kiži, however in the few years it has also spread to the Northern Altai Republic.

Though traditionally considered one language, Southern Altai is not fully mutually intelligible with the Northern varieties. Written Altai is based on Southern Altai, and according to Ethnologue is rejected by Northern Altai children. In 2006, a Cyrillic alphabet was created for the Kumandy variety of Northern Altai for use in Altai Krai.

Dialects are as follows:

Closely related to the northern varieties are Kondom Shor and Lower Chulym, which have -j- for proto-Turkic inter-vocalic *d, unlike Mras Shor and Middle Chulym, which have -z- and are closer to Khakas.
