Commentary
The suggested etymologies for Hungarian honn (and the coined hon, derived from it) are uncertain, as both TESz and EWUng admit. However, a new explanation can be suggested: hon(n) could be regularly derived from Proto-Uralic *kunV, reflected in Khanty V kŏṇ, DN χŏn, O χŏn 'Bauch' and Komi ki̮ne̮m 'Bauch' (see Uralonet). The Khanty and Komi words denote 'belly', but it can be assumed that the meaning of Hungarian 'at home' could have developed from 'inside', which would not be far from the meaning 'belly'. It is also possible that a more general meaning 'internal parts' or 'inside something' was the meaning of the Uralic word.
It has already been suggested that *kunV is reflected by Hungarian compounds like Old Hungarian iunhum 'Herz, Sinn, Leber, Lende'. This is a plausible idea.
Conclusion
This new etymology involves less phonological uncertainty than the previous explanations.
