The Nakh-Daghestanian language family is a group of languages primarily spoken in the North Caucasus region, particularly in Dagestan, a republic of Russia. This family is divided into two main branches: the Nakh languages, which include Chechen and Ingush, and the Daghestanian languages, which consist of several languages such as Avar, Tuvan, and Lezgian. These languages are known for their complex phonetic systems and rich morphology. They feature a variety of consonant sounds and often have multiple grammatical cases. The Nakh-Daghestanian languages are an important part of the cultural identity of the peoples in this region.
