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.
The Northeast family is assumed to include the
Nakh languages (
Batsbi,
Chechen, and
Ingush), which were formerly classified as a separate 'North-central Caucasian' family.
The Ibero-Caucasian group would also include three extinct languages:
Hattic, which has been connected by some linguists to the Northwest (Circassian) family, and
Hurrian and
Urartian, which have been connected to the Northeast (Nakh-Dagestanian) family. See the articles on the two families for more discussion.
Family status
The affinities between the three families above are still disputed. A connection between the Northeast and Northwest phyla is seen as likely by many linguists; see the article on the
North Caucasian languages for details.
On the other hand, there are no known affinities between South Caucasian and the northern languages, which are two unrelated phyla even in
Greenberg's deep classification of the world's languages. "Ibero-Caucasian" therefore remains at best a convenient geographical designation, not a linguistic phylum.
Family name
The "Iberian" in the family name refers to
Caucasian Iberia — a kingdom centered in Eastern
Georgia which lasted from the 4th century BC to the 5th century AD, and is not related to the
Iberian Peninsula. Because of its historical connections to the country of Georgia, the use of "Iberian" as a blanket term including the northern families is deprecated by some speakers of those languages.
