Abkhaz language
The Abkhaz language belongs to the isolate Northwest Caucasian language family, also known as Abkhaz–Adyghe or North Pontic family, which groups the dialectic continuüm spoken by the Abaza–Abkhaz (Abazgi) and Adyghe ("Circassians" in English). Abkhazians are closely ethnically related to Circassians. Classical sources speak of several tribes dwelling in the region, but their exact identity and location remain controversial due to Abkhaz–Georgian historiographical conflict.
