Comments: The Akhv. word (=uq-, Tseg. =uχ-) is attested only in Gudava 1964, 98; since the common verb for "die" in Akhv. is =iƛ̣- q.v., we may assume that the root =uq- has here some specific meaning (most probably - 'to die out (plur.)' which it means in other Dagestan languages).
Akhv. =uq- reflects PA *=iqʷ- (stem 1), while Av. χʷé- goes back to *qʷV- (stem 2).
