Commentary
UEW considers the Ugric etymology uncertains and also notes that the words in different Proto-Mansi dialects point to different Proto-Mansi vowels. UEW also mentions the possibility of onomatopoetic origin of the alleged Ugric cognates.
One could also add that the Khanty, Mansi and Hungarian words have quite different meanings. Because the alleged Proto-Ugric word is only attested as part of derivatives in Hungarian and Mansi, it is difficult to reconstruct the original meaning, however.
The reconstruction *sarɜ in the UEW cannot account for the Hungarian word as *a > o would be irregular (there are examples of such a change but this was probably regular only before *ć or ćk). As the reconstruction of the Proto-Mansi word is problematic and the words show contradictory vowel correspondences, it is also obvious that this Proto-Ugric reconstruction does not fit the Mansi word.
Conclusion
Because of phonological and also semantic problems the Proto-Ugric etymology should be rejected.
