Commentary
See also Etymologiadata:imsm:arpa
Many sources present both the inherited Uralic (Finno-Ugric etymology) and the Turkic loan etymology for the Turkic word (see most recently WOT, Honti 2017, Róna-Tas 2017). However, already MSzFE, which likewise presents both possibilities, noted that the relationship Fi a ~ Hu o is not regular (Hungarian o would not be the regular reflex of Proto-Uralic *a). Also the competing loan etymologies for the Finnic and Saami word (← Proto-Germanic *arƀa- or arƀa-z, > Old Swedish arf, arver ’maaomistus, perintö’; Koivulehto 1972: 249) and the Hungarian word make the Uralic etymology unlikely. The Turkic origin of the Hungarian word listed by WOT is plausible both phonologically and semantically (see WOT 657–659 for discussion on earlier, more problematic Turkic donor forms).
Conclusion
Hungarian orvos is probably borrowed from Turkic.
