Proto-Lezghian: *cowɨl:
Meaning: 1 autumn 2 spring
Lezghian: zul 1
Tabasaran: č̌ul 1
Agul: cul 1
Tsakhur: cuwul / cɨwɨl 1
Archi: sot:-aqI 1
Udi: žIoʁul 2 (?)
Comment: Cf. also Lezg. Yark. gül, Akht. žul, Khl. zul ( < Proto-Lezg. *zʷɨl). The Ud. form raises some doubts (both semantically and phonetically). The word belongs to the 4th class in all class-distinguishing languages. The Archi form is a historical locative (cf. the pure root in Arch. sot 'in autumn'). Voicing in Lezg. was probably caused by an early contraction (*cowɨl: > *cʷɨl), with following spirantization (*cʷɨl > *s:ʷɨl, regularly > *zʷɨl).
