Comments:Дыбо 10, AKE 15, EAS 58. Phonetically a rather complicated case because of the rare medial cluster *-kr- with non-standard reflexes. Turkic, Mongolian and probably Korean reflect a suffixed form *bukrV-č`V (MKor. phắs = *phắč < *bukVr-č`V); medial -k- in the cluster had disappeared in PT and yielded -ɣ- in Mong. Another derivative from the same root may be the Turk.-Mong. name of various kinds of berries: PT *bögürtlen 'blackberry' etc., Mong. *böɣerel(ǯi)gene 'raspberry etc.' (KW 56).
