North Caucasian Languages - Internal Classification

Internal Classification

Among the linguists who support the North Caucasian hypothesis, the main split between Northeast Caucasian and Northwest Caucasian is considered uncontroversial. Problems arise when it gets to the internal structure of Northeast Caucasian itself. So far no general agreement has been reached in this respect. The following classification is based on Nikolayev & Starostin (1994):

Abkhazo-Adyghean
Hattic
Nakh–Daghestanian
Nakh
Hurro-Urartian
Daghestanian
Avar–Andi–Dido
Lak–Dargwa
Lezgic

Famous quotes containing the word internal:

    I believe that there was a great age, a great epoch when man did not make war: previous to 2000 B.C. Then the self had not really become aware of itself, it had not separated itself off, the spirit was not yet born, so there was no internal conflict, and hence no permanent external conflict.
    —D.H. (David Herbert)
