Fionnáin

Fionnáin is a relatively uncommon given name of Irish origin. The name is a masculine form derived from the Old Irish name Fionn, which means "fair" or "white." This etymology connects Fionnáin to a lineage of prominent figures in Irish mythology, most notably Fionn mac Cumhaill, the legendary warrior and leader of the Fianna. The association with Fionn mac Cumhaill lends the name connotations of heroism, strength, and wisdom.

While not as widely used as some other Irish names, Fionnáin has maintained a presence throughout Irish history and continues to be chosen by parents seeking a name with deep cultural roots and a positive meaning. Variations in spelling can occur due to the transliteration of Irish Gaelic into the Latin alphabet. The pronunciation typically emphasizes the first syllable. The name's enduring appeal lies in its connection to Irish heritage and its evocative meaning.
