Proto-Circassian (or Proto-Adyghe–Kabardian) is the reconstructed common ancestor of the Adyghean and Kabardian languages.

Phonology

Consonants

The consonant system is reconstructed with a four-way phonation contrast in stops and

affricates An affricate is a consonant that begins as a stop consonant, stop and releases as a fricative consonant, fricative, generally with the same place of articulation (most often coronal consonant, coronal). It is often difficult to decide if a stop a ...

, and a two-way contrast in

fricatives A fricative is a consonant produced by forcing air through a narrow channel made by placing two articulators close together. These may be the lower lip against the upper teeth, in the case of ; the back of the tongue against the soft palate in th ...

Aspirated consonants to plain

In the Proto-Circassian there was a series of aspirated consonants that survived in the Shapsug and Bzhedugh dialect while they became plain consonants in the other dialects. * → * → * → * → * → * → * → * → * → * →

Velar consonants to palato-alveolar

In the Proto-Circassian language there exist a palatalized voiced velar stop , a palatalized aspirated

voiceless velar stop The voiceless velar plosive or stop is a type of consonantal sound used in almost all spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is , and the equivalent X-SAMPA symbol is k. The sound is a ver ...

and a palatalized velar ejective . The consonants гь , кь and кӏь survive in the Shapsug dialect, in the Besleney dialect and in the Kabardian Uzunyayla dialect. In other Circassian dialects they were merged with the palato-alveolar consonants дж , ч and кӏ respectively.Studia Caucasologica I page 11

Affricate to fricative

In the Abzakh and the Kabardian dialects, the affricate

postalveolar consonant Postalveolar or post-alveolar consonants are consonants articulated with the tongue near or touching the ''back'' of the alveolar ridge. Articulation is farther back in the mouth than the alveolar consonants, which are at the ridge itself, but ...

Labialized voiceless velar fricative

Proto-Circassian had a labialized

voiceless velar fricative The voiceless velar fricative is a type of consonantal sound used in some spoken languages. It was part of the consonant inventory of Old English and can still be found in some dialects of English, most notably in Scottish English, e.g. in ''l ...
