fiú (Hungarian)

Where does "fiú" come from?

The Hungarian noun 'fiú', meaning 'boy', 'son', or 'boyfriend'[1], descends from Old Hungarian 'fioɣ' or 'fió'[1]. This form combines the original stem 'fi' with the archaic diminutive suffix '-ú'[1]. The root is akin to Proto-Uralic '*pojka', meaning 'son' or 'boy'[1], a heritage shared with cognates such as Finnish 'poika'[1], Northern Mansi 'пыг'[1], and Udmurt 'пи'[1]. Despite surface similarities, it is a false cognate of the Romanian word 'fiu'[1].

Open questions

• The Proto-Uralic form is not attested in Samoyedic except possibly as a borrowing, and it has been suggested that the term derives from a shorter stem. [2]
