Cognates suggested in earlier research
Khanty: East (Vj) pŏγ, South (DN) pŏw 'Nadelöhr', North (O) pŏw 'Angel (des Messers)' < PKh *puγ
Mansi: East (KU) juntəp-pop, North (So) jūntəp-pup 'Nadelöhr' < PMs ?
Commentary
UEW considers the Ugric etymology convincing, even though the problems with phonology are noted: Khanty w/γ cannot regularly reflect Ugric *kk, and the Mansi "cognate" lacks reflexes of *γ (UEW assumes this might have become lost before p). Due to these phonological problems, there is no reason to assume we are dealing with a Proto-Ugric word: also the semantic connection of the Hungarian and Ob-Ugric words is rather vague.
Conclusion
No PUg word can be reconstructed.
