Proto-North Caucasian: *=ǟwčĂ
Meaning: to emit, pour; vomit
Notes: The medial *-w- accounts for PN *-b- and the labialisation in PA and PWC (*-čw- can not be reconstructed - it would give a quite different set of reflexes). The original meaning must have been "to emit, pour" (whence, a) "to wash, to bathe", b) "to throw, strew; to leap", c) "to vomit" - meanings constantly recurring in different subgroups). It is interesting to note that many languages have prefixed *l- or suffixed *-l- ( < *ɫ). It may mean that *ɫ- was originally part of the root (*ɫǟwčĂ) and was later reinterpreted as a preverb.
