Proto-Lezghian: *ʔerχʷa
Meaning: 1 to comb 2 to scratch, scrape 3 comb (n.)
Lezghian: čuχʷa- 2
Tabasaran: ǯ̌-u=χ- 1
Agul: ž-irχ- 1
Tsakhur: giw-a=χa- 1
Archi: =eχ:a- 1
Udi: oχ 3
Comment: Cf. also Tab. Düb. ǯi=χ-, Ag. Bursh. ǯurχa-, Arch. dur. =erχ:u-r. All reflexes point uniformly to *-χʷ-, except Arch. -χ:-. Tense -χ:- in Archi should be probably explained by the influence of gobχ:a-s 'to scratch, scrape' (or the Lak. form =uχ:Ia-n ?). Lezg., Tab. and Ag. reflect a stem with an expressive preverb (*č:- or *č-).
