Notes: Reconstructed for the PEC level. In the Anlaut there occurs a variation *p-/b- (probably *p- > *ṗ- through assimilation and then again > *b- through dissimilation - a process typical for roots containing two stops).
The meaning 'hollow stalk, tube' in Lak. provides a necessary semantic link between 'vulva' in Western languages and 'penis' in Aghul; cf. also the meanings in Darg. dialects.
