Комментарии:Correspondences are basically regular, with the following comments: in Turkic one has to suppose secondary delabialization *bij- < *büj- ( < *büb-); the Kor. form pjàpắi- must be denominative, derived from a noun *pjàpắ- < *pibV-pu- < *pi̯ubi-p`u- ( = PTM *pubu-pu-). Cf. *p`i̯ṑpo: the two roots are sometimes hard to distinguish.
