Proto-Lezghian: *ʎ:ʷɨrV-m ( /-n)
Meaning: 1 bridle 2 leather rope
Tabasaran: furin 1
Agul: mufur 2
Rutul: nixrä-b 1
Archi: duʎ:ur 1
Comment: 4th class in Rut. and Arch. Cf. also Tab. Düb. furu, Ag. Bursh. muf:ur, Rut. Ikhr. rɨxnä. The most simple and archaic root structure is preserved in Tab. Düb. furu. Most other languages reflect a form with suffixed *-n or *-m and multiple metatheses (*ʎ:ʷɨrV-n > Tab. furin, with metathesis > Rut. nixrä-b (-b is a recently added plural suffix), Ikhr. rɨxnä; *ʎ:ʷɨrV-m > *mɨʎ:ʷVr > Ag. mufur, Bursh. muf:ur). A special case is Arch. duʎ:ur : it either reflects *ʎ:ʷɨrV with suffixed (plural) -r - *ʎ:ʷɨrV-r > (with metathesis) *rɨʎ:ʷVr > duʎ:ur, or - which is more probable in view of the external evidence - reflects the stem *ʎ:ʷɨrV with a prefixed *rV- (*rV-ʎ:ʷɨr > duʎ:ur), cf. PD *ʔur-x:ʷir, Cham. raʎir.
The Agul word certainly belongs here; however, its aberrant meaning 'leather rope' may be due to a contamination with another PEC root (see *Hxǝ̄mV̆ 'leather rope'), which should have yielded *ʎamV(-r) in PL, but is not attested.
