Notes: Most languages reflect the stem *-iwƛ̣Ĕ- (with class prefixes; the variant without class prefixes is probably reflected in PN dur. stem *la- with vowel reduction); the Ablaut grade *-uwƛ̣Ĕ is reflected in some Lezg., And. languages and in Darg. See Абдоков 1983, 165.
Some Lezghian languages reflect a derivate *ʔiƛ̣i-n > *ƛ̣in meaning 'oath' (cf. Lezg. q̇in, Tsakh. ḳin). It seems thus quite proper to compare HU forms: Hurr. el(a)mǝ 'oath', Urart. elm-u/ošǝ 'vow' (see Diakonoff-Starostin 1986, 33).
