Proto-North Caucasian: *moƛ̣_ōrV
Meaning: a k. of foliage tree
Notes: An interesting root, both phonetically (note the peculiar metathesis in PTs) and semantically (note the intricate semantic developments in PL; cf. also an interesting development "peach" > "fruit stone" - not vice versa - in Akhv.). It is hard to establish the precise meaning in PNC: the only obvious fact is that the root denoted some kind of a foliage tree, which was often used for construction purposes (cf. the meanings in Tsezian and Lezghian languages) and probably resembled a peach-tree (cf. the meaning in Av.).
See Abdokov 1983, 109 (Akhv. : Kab.; Chech. lag, also cited by the author, has no relation to the present root).
