Proto-Lezghian: *ʔirχ:ʷV / *χ:irχ:ʷV
Meaning: 1 to saw 2 saw
Tabasaran: q-a=χI- 1
Agul: d-irχ- 1
Rutul: darχilaq 2
Tsakhur: ajχā 2
Archi: χ:uχ:u-bos 1
Comment: In Tab. the root is used only with preverbs (q-, ald-); pharyngealization is probably secondary (expressive). The Lezghian languages reflect two main nominal derivates from this root:
1) *t:-irχ:ʷV-l / *t:-irχ:ʷV-n (cf., besides Rut. darχilaq, also Tab. durχin, Ag. duruχal);
2) *ʔarVχ:(ʷ)V-ra > Tsakh. ajχā (Gelm. ajχewa).
Cf. also Arch. χ:uχ:ǝṭiḳi 'saw' - which is obviously derived from χ:uχ:u- (although it may have been influenced also by the related Lak. χ:uχ:uṭi 'file').
