Comments: A compound of *le- (a reduced form of PSC *ʡwĭlʡí 'eye') + Bsq *hagin 'tooth' (q.v.). The intervening *-t- is a fossilized oblique marker, familiar from other Bsq compounds (cf. sutargi 'firelight' < *śu + *-t- + *argi, etc.). Western Bsq betagin is an innovative reinterpretation, based on Bsq *begi 'eye' (q.v.).
