Proto-West-Caucasian: *χ́V
Meaning: more
Abkhaz: ájħa
Abaza: a(j)ħa
Adyghe: nāh
Kabardian: naχ
Ubykh: ća-χ́
Comments: PAT *(ajǝ)-ħa (with a reciprocal prefix); PAK *ná-χ́ǝ (with a deictic prefix na-). In Ub. ća- is a comparative prefix. See Shagirov 1,281 with literature (justly singling out the common WC root morpheme *χ́V "more"; however, Shagirov's linking this root with PAT *ħaraḳǝ 'high' is probably wrong).
