Commentary
The Ugric etymology found in the UEW is impossible: neither the Khanty nor the Hungarian word reflects a pre-form *purV- regularly.
Aikio (2018) argues that far reflects Proto-Uralic *pončǝ. This explanation is convincing, as a parallel case to the development *nč > Hu r is Hu köröm 'nail' < PU *künči.
Conclusion
Aikio's Proto-Uralic explanation is convincing.
