Godoberi or Ghodoberi is spoken in southwestern Dagestan in Russia by about 3,000 people. It is a member of the Avar-Andic subgroup of Northeast Caucasian languages. There are two main dialects: Godoberi and Zibirhali, which differ mainly in pronunciation. Godoberi has borrowed words from Avar, Turkish and Arabic, and particularly from Russian during the 20th century. The most closely-related languages to Godoberi are Chamalal and Botlikh.
The main written language of Godoberi speakers is Avar - their own language is rarely written.
