The Family of Ibero-Caucasian Languages

The term Ibero-Caucasian (or Iberian-Caucasian) was proposed by Georgian linguist Arnold Chikobava for the union of the three language families that are specific to the Caucasus area, namely South Caucasian, also called Georgian or Kartvelian; Northwest Caucasian, also called Abkhaz/Adygh or Circassian; Northeast Caucasian, now called Nakh-Dagestanian.
