Proto-Lezghian: *ʔiχV
Meaning: to fly
Tabasaran: ṭ-irχub
Tsakhur: al-iχas
Comment: The verb belongs to the strong class. The Tab. form contains an intensive preverb ṭ-: cf. also Tsakh. hi-ṭ-i-χa-s 'to row'.
In Ag. Bursh. we have alt-χi-s 'to fly' - which is presently easily analysed as preverb alt- + χi- 'to go' (see PL *ʔiχ(:)e-); but since historically these are quite different roots, it is probably a later merger.
