Proto-North Caucasian: *bēng_wă
Meaning: rock, mountain; ravine
Notes: For PEC an intermediate form *bēnŁ_wă must be reconstructed (with *Ł regularly < *g in a tense word). In PL we must assume a metathesis (*ƛ̣:ʷema < *meƛ̣:ʷa); otherwise the correspondences are regular. PWC demonstrates a usual delabialisation (*ɣʷ > w) after a labial consonant.
