Proto-West-Caucasian: *b-č̣́a
Meaning: guest
Adyghe: ħāč̣́a
Kabardian: ħaṣ́a
Ubykh: pč̣́a
Comments: PAK *ħa-č̣́á. The component *ħa- is not clear etymologically (perhaps related to another PEC root for "guest", *χ_alHV?). Still the relationship between the AK and Ub. words can not be debated, and Trubetzkoy's (1921) hypothesis about PAK *ħač̣́a being borrowed from Iranian *haxay 'friend' is absolutely groundless.
