Proto-Lezghian: *q:Iurt:iƛ̣:an
Meaning: pillow
Lezghian: qüc:ügan
Agul: R̀urdek:in
Rutul: ʁurdigän
Tsakhur: ʁunelek
Kryz: q:uǯukan (Al.)
Budukh: q:üškü-d
Comment: Cf. also Lezg. Khl. q:ücügen, Ag. Burk. R̀ardek:en. 3d class in Rut., Tsakh. and Kryz., 4th class in Bud. A long word with rather expected metatheses and dissimilations; nevertheless, the PL form is sufficiently well reconstructable. Major irregularities: Lezg. -g- instead of (lit.) -ḳ-, (Khl.) -k:- - a result of early deglottalisation (*-ƛ̣:- > *-ƛ:-); Tsakh. ʁunelek (with a variant ʁulenik; cf. also Gelm. ʁunanik, Tsakh. proper q:uńanik) < *q:udinVƛ̣: / *q̇:ulinVƛ̣: (note the early secondary lateralisation -d- > -l- under the influence of *-ƛ̣:, which later regularly changed to -k); loss of pharyngealisation in the Eastern area (for PL it must be reconstructed on the Lezg. and Ag. evidence).
Since the meanings 'pillow' and 'sack' are often interchangeable, it seems tempting to link with this root also Arch. ƛ̣:ut:ali 'sack' - possibly an assimilative development from the expected *qIut:aƛ̣:i(n).
In Proto-Shakh-Dagh the word must have sounded *q:uǯiḳ:in (cf. modern forms: Kryz. q:uǯukan, Bud. - with some irregularities - q̇:üšküd). This form was most probably borrowed in Khin. iχčiḳin 'pillow' (which can not be a genuinely related form).
