The Tsezic languages (also called Didoic languages) form one of the seven main branches of Northeast Caucasian language family. It branches into Tsez–Hinukh and Bezhta–Hunzib–Khwarshi, according to the latest research. They were formerly classified geographically into East Tsezic (Hinukh, and Bezhta) and West Tsezic (Tsez, Khwarshi, and Hunzib). The Avar language serves as the literary language for speakers of Tsezic languages.
