пчъын

Adyghe

From Proto-Circassian *pč:ǝ- (Nikolayev / Starostin) or *bč:ǝ- (Šagirov). Cognate with Kabardian бжын (bžən). Šagirov following Rogava remarks that the initial consonant may be a frozen grammatical class marker and compares the stem with several Northeast Caucasian words. The comparison is accepted by Nikolayev / Starostin who reconstruct Proto-Northwest Caucasian *p-č́:ʷǝ (“to count”) and propose a connection with Proto-Northeast Caucasian [Term?] (“to count; to understand”).
