Proto-Tsezian: *bǝz(:)ɔ
Meaning: hoe, pick
Tsezi: bizo
Ginukh: bezo
Khvarshi: bizo (Radzhibov)
Bezhta: boza
Gunzib: bozo
Comments: PTsKh *bǝzo; PGB *boz[ɔ]. In PGB *-ǝ- would be regularly expected; -o- (or, in fact, Gunz. -o- - because Bezht. -o- goes back both to *o and to *ǝ) can be a result of labial assimilation.
