Proto-IE: *puk(')- ?
Meaning: fox
Old Greek: pl. phoûai = alṓpekes Hsch. < *pusā̆ < *pukjā̆ - if this form is Laconian one, then -s- > -0-, cf. Lacon. phoûiks = phǘsiŋks Hsch.; perhaps also ph- < *p- because of the medial *-h-.
Russ. meaning: зверек (лиса)
Comments: Differently in Pok. The comparison with Tokh B pako 'tail' is doubtful.
