Caucasian languages are a diverse group of languages spoken primarily in the Caucasus region, which lies between the Black Sea and the Caspian Sea. These languages are classified into three main families: Northwest Caucasian, Northeast Caucasian, and Kartvelian. Each family includes several languages, such as Abkhaz, Chechen, and Georgian, which are known for their complex phonetic systems and rich morphological structures. The Caucasian languages are notable for their unique features, including a high number of consonants and a variety of vowel sounds. They are primarily spoken by various ethnic groups in the region, contributing to the cultural and linguistic diversity of the Caucasus. Despite their differences, these languages share some common characteristics, reflecting the historical interactions among the peoples of this area.
