fið

Fiú is a Hungarian noun meaning a male child or a young male person. It is used for boys and, in informal contexts, for younger male acquaintances. The definite article is used in phrases like a fiú (“the boy”), and the plural is fiúk (“the boys”). The word is masculine and follows standard Hungarian noun declension; it appears in common compounds such as kisfiú (little boy) and felnőtt fiú (adult boy, i.e., young man).

Pronunciation is approximately [ˈfuː], with the long ú indicating a lengthened u sound.

Etymology is uncertain; it is generally regarded as native to Hungarian with attestations in medieval texts. The term is a basic part of the vocabulary for gender and age categories in Hungarian.

In usage, fiu can function as a neutral or affectionate term of reference. It is commonly used in everyday speech, in child-related contexts, and also as a casual form of address, for example, Hé, fiú! Depending on tone and context, it can be friendly and informal or potentially inappropriate in formal settings when referring to an unrelated adult.

The word contrasts with lány (girl) and gyerek (child). In compounds, it appears in kisfiú (little boy) and in expressions like jó fiú (good boy). For adult male counterparts, Hungarian typically uses terms such as férfi or férfiú, depending on formality and context.
