Meaning & Origin of Una

Una has dual origins, functioning as both an Irish and a Latin name. In Irish, Una (sometimes spelled Oona or Oonagh) derives from the Old Irish "uan" meaning "lamb," and the name appears prominently in Irish mythology as Oonagh, the queen of the fairies in some traditions. In Latin, Una simply means "one," suggesting uniqueness. Edmund Spenser used the name in his epic poem The Faerie Queene (1590), where Una represents Truth and the one true church. The Irish pronunciation is typically "OO-nah," while the English and Latin pronunciation is "YOO-nah." The name has remained steadily used in Ireland and has gained broader appeal for its simplicity and elegance.
