Proto-Northwest Caucasian language

Proto-Northwest Caucasian (sometimes abbreviated PNWC), also Proto-Adyghe-Abazgi or Proto-Adyghe-Abkhaz, is the reconstructed common ancestor of the Northwest Caucasian languages.

Phonology

Vowels

Proto-Northwest Caucasian, just like its descendants, had a very small vowel inventory, most commonly reconstructed as consisting of 2 vowels: /a/ and /ə/. Some degree of allophony might have existed, especially near labialized and palatalized (or both) consonants.

Some scholars assume that the rich consonantal distinctions appeared from a formerly rich vowel inventory, so **/Cy/ would result in */Cʷʲə/, **/Co/ in */Cʷa/ (or possibly /Cˤʷa/), and so on. However, this view is doubted due to the tendency of vowel systems to get richer over time, and the opposite being much more rare.

Consonants

There was a primary four-way distinction of almost all obstruents in Proto-Northwest Caucasian. The following variations have been proposed:

• Geminate /Cː/, plain /C/, ejective /Cʼ/ and voiced /C̬/;
• Unaspirated /C˭/, aspirated /Cʰ/, ejective /Cʼ/ and voiced /C̬/;
• Fortis /C͈/, lenis /C͉/, ejective /Cʼ/ and voiced /C̬/.

The only living descendants to have kept the 4-way distinction are the Shapsug and Bzhedug dialects. They both feature an unaspirated /C˭/, aspirated /Cʰ/, ejective /Cʼ/ and voiced /C̬/ distinction, where all the remaining languages have merged them to plain /C/, ejective /Cʼ/ and voiced /C̬/.

Additionally, there also were distinctions in labialization, palatalization and glottalization (and, depending on the analysis, aspiration), with combinations of those also possible, such as in case of /qˤʷʲː/.

1. In Circassian and Abkhaz, gʷǝ is heart and in Ubykh it's gʲǝ.

The most noticeable changes are:

• The uvular consonants (/χ/ /ʁ/ /χʷ/ /ʁʷ/) become pharyngeal consonants (/ħ/ /ʕ/ /ħʷ/ /ʕʷ/) in the Proto-Abazgi language.
