Meaning and origin of Fynn
Fynn is an Irish name that is usually said to mean “variant of Finn, fair”.
Fynn is a spelling of Finn, an Irish name meaning "fair" or "white," from the Old Irish fionn. It is linked to Fionn mac Cumhaill, the great hero of the Fenian Cycle, and Finn has also been used in Scandinavia and Germany, where Fynn is a well-known spelling. The y gives the short name a slightly Nordic or German look without changing the sound, FIHN. It feels bright and outdoorsy and works as a full name or as a nickname for Finnegan or Finley.
