Comment: The Ud. form regularly goes back to *meq̇Iel < *nVq̇Iʷel. The Arch. and Ud. forms stand quite apart from other Lezghian languages, which reflect a simple root *q̇Iʷel (q.v.). We may think, that this specific Arch.-Ud. isogloss is a reflection of an old compound *nVq̇IʷV-q̇Iʷel, not preserved in other languages (otherwise we would have to deal with a fact of a quite irregular loss of the first syllable in all Lezghian languages except Arch. and Ud.).
