Grammar

Northwest Caucasian languages have rather simple noun systems, manifesting only a handful of cases at the most, coupled with highly agglutinative verbal systems so complex that virtually the entire syntactic structure of the sentence is contained within the verb. All finite verbs are marked for agreement with three arguments: absolutive

s and a four-way place contrast among sibilants. It was the only Northwest Caucasian language never to have a literary form.

Relationship to other language families

A number of factors make the reconstruction of the Northwest Caucasian proto-language problematic:
  • most roots in Northwest Caucasian languages are monosyllabic, and many are single consonants;
  • the sound change
    Sound change
    Sound change includes any processes of language change that affect pronunciation or sound system structures...

    s are often intricate, and a large number of consonants and sibilant contrasts provides further complexity;
  • ablaut was extensive and still plays some part in the modern languages;
  • borrowings between languages of the family were frequent;
  • extensive homophony
    Homophone
    A homophone is a word that is pronounced the same as another word but differs in meaning. The words may be spelled the same, such as rose and rose , or differently, such as carat, caret, and carrot, or to, two, and too. Homophones that are spelled the same are also both homographs and homonyms...

For these reasons, Proto–Northwest Caucasian is widely accepted as being one of the most difficult proto-languages to deal with, and it is therefore more difficult than most to relate to other families.
