The Caucasian language family refers to a group of languages spoken primarily in the Caucasus region, which lies between the Black Sea and the Caspian Sea. This family is divided into three main branches: Northwest Caucasian, Northeast Caucasian, and South Caucasian. Each branch contains several languages, many of which are unique to specific ethnic groups in the area. Languages in the Caucasian family are known for their complex phonetic systems and rich consonant inventories. Some notable languages include Abkhaz, Chechen, and Georgian. These languages are not closely related to the Indo-European or Turkic language families, highlighting the linguistic diversity of the region.
