Udi Language

The Udi language, spoken by the Udi people, is a member of the Lezgic branch of the Northeast Caucasian language family. It is believed an earlier form of it was the main language of Caucasian Albania, which stretched from south Dagestan to current day Azerbaijan. The Old Udi language is also called the "Caucasian Albanian" language and possibly corresponds to the "Gargarian" language identified by medieval Armenian historians, while modern Udi is known merely as the Udi language.

The language is spoken by about 5,000 people in the Azerbaijani village of Nij in Qabala rayon, in Oghuz rayon, as well as in parts of the North Caucasus in Russia. It is also spoken by ethnic Udis living in the villages of Debetavan, Bagratashen, Ptghavan, and Haghtanak in Tavush Province of northeastern Armenia and in the village of Zinobiani (Oktomberi) in the Kvareli District of the Kakheti province of Georgia.

Udi is endangered, classified as "severely endangered" by UNESCO's Atlas of the World's Languages in Danger.
