Commentary
The Ugric etymology is presented as uncertain in UEW and EWUng due to semantic difficulties and the possibility that the Ob-Ugric words can be of onomatopoetic origin. Already Barczi (1943: 176) rejected the Ugric etymology. Also Zhivlov (2016: 296) mentions the possibility that the Ob-Ugric words can be onomatopoetic. He also considers the relation to Hungarian könyörög- improbable.
The phonological relations between the Ob-Ugric and Hungarian words are unclear. Hungarian ö often goes back to Proto-Ugric/Uralic *ü, and also often to *i, although in the latter case there usually is variation ë ~ ö within Hungarian; in this case such variation is not found in modern Hungarian, but it is unclear whether Old Hungarian attestations like kenyerewle reflect an illabial vowel. The Ob-Ugric words cannot reflect *ü regularly, but Khanty *käṇəγ- could reflect PUg *kiṇ-. However, it would be difficult to derive Mansi *kīnəγ- from such a form. The relationship between the Khanty and Mansi words requires further research, but it is quite clear that it is impossible to reconstruct a Proto-Ugric form that would account for all of the suggested reflexes. The Proto-Ugric reconstruction *kenɜ- in the UEW is in any case impossible.
A Turkic etymology has been suggested by Palló (1982: 135–136) who assumes a source form *könür-, based on Old Turkic kön- 'to straight'; however, WOT (1191-1192) rejects this possibility, as the derivative *könür- is not attested and also the semantic connection is unclear. WOT considers the Hungarian to be of unknown origin.
Conclusion
The Proto-Ugric etymology should be rejected, and the origin of the Hungarian word-family könyörül', könyörög remains unclear.
