Commentary
The etymology is very problematic, as the various Hungarian forms listed in the UEW cannot be related to each other through regular derivational means. EWUNg notes that éh is probably not related to jonh, joh etc., and also íh ~ ih is problematic (éh is derived from the verb e- to eat by EWUng). The explanation found in UEW and EWUng that the variant jonh is originally a compound, the latter part of which involves a reflex of *kunV 'stomach', seems probable, but it is unclear what is exactly the first member of this compound and should its background be reconstructed. Even the Ob-Ugric forms are not regularly related to each other, and Honti (1982) does not give a Proto-Ob-Ugric reconstruction.
Conclusion
Various phonological problems make it impossible to reconstructs a Proto-Ugric word. More research on the etymology of the alleged cognates is needed.
