Proto-Circassian language

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

Phonology

Vocalism and accent

In bisyllabic roots, two possible places of accent are reconstructed, with the following development of structures in descendant languages:

PAK	Adyghe		Kabardian	Examples
	Standard	Shapsug		Meaning	Standard Adyghe	Shapsug	Kabardian
*CáCa	CaːC	CaːCa	CaːCa
*CáCǝ	CaC	CaC	CaC

*CǝCá	CǝCa	CǝCa	CǝCa	gold house cold	дышъэ [dəʂa] унэ [wəna] чъыӏэ [t͡ʂəʔa]	дышъэ [dəʂa] унэ [wəna] чьыӏэ [t͡ɕəʔa]	дыщэ [dəɕa] унэ [wəna] щӏыӏэ [ɕʼəʔa]

In other words, Adyghe retains the distinction between *a and *ǝ in the 2nd syllable, if it was originally stressed; the 2nd syllable vowel is dropped in originally unstressed syllables. Kabardian retains the distinction uniformly, by dropping *ǝ but not *a. Both groups retain the quality distinction in the first syllable, and additionally display a long vowel in roots of the original shape *CaCa (regardless of stress).

Consonants

The consonant system is reconstructed with a four-way phonation contrast in stops and affricates, and a two-way contrast in fricatives.

Labialized palato-alveolar цу, су, зу and сӏу

The Proto-Circassian language did not had labiodental consonants (ф [f] and в [v]). There existed a series of labialized alveolar sibilant affricates and fricatives: *[tsʷ] ⟨цу⟩, *[sʷʼ] ⟨сӏу⟩, *[sʷ] ⟨су⟩, *[zʷ] ⟨зу⟩. In Adyghe Temirgoy dialect they became *[tsʷ] ⟨цу⟩, *[ʃʼʷ] ⟨шӏу⟩, *[ʃʷ] ⟨шъу⟩, *[ʒʷ] ⟨жъу⟩. In Shapsug, Bzhedug and Abzakh dialects of Adyghe they become labiopalatalized *[tɕʷ] ⟨чъу⟩, *[ʃʼʷ] ⟨шӏу⟩, *[ʃʷ] ⟨шъу⟩, *[ʒʷ] ⟨жъу⟩, and in Kabardian they become labiodental consonants *[v] ⟨в⟩, *[fʼ] ⟨фӏ⟩, *[f] ⟨ф⟩, *[v] ⟨в⟩.

Other noticeable changes

Uvular affricates

The consonant aspirated voiceless uvular stop [qʰ] ⟨къʰ⟩ and its labialized counterpart [qʰʷ] ⟨къʰу⟩ survived in Bzhedug. In the Temirgoy dialect they become къ [q] and къу [qʷ] while in some Shapsug dialects they become хъ [χ] and хъу [χʷ]. In Kabardian they became affricate voiceless uvular affricate [q͡χ] ⟨кхъ⟩ and labialized voiceless uvular affricate [q͡χʷ] ⟨кхъу⟩.

Lateral affricates
