What is the meaning of the name Oona ?

The baby name Oona is a Female name , 2 syllables long and is pronounced OO-nə, OO-nah; IPA: /ˈuːnə/.

Oona is Irish in Origin.

Oona is the Anglicized Irish form of Úna, a Gaelic feminine name likely derived from uan, "lamb," a symbol of gentleness and protection. Spellings vary widely: Úna in Irish, Una in English, Oona and Oonagh as phonetic Anglicizations; in Finland, Oona has been adopted directly. While Una in English literature can also echo Latin unus, "one," that etymology is separate from the Gaelic root, though the spellings have overlapped for centuries.

The name appears in Irish tradition and folklore - most famously as Oonagh, the clever wife of Fionn mac Cumhaill in the Giant's Causeway tales - and occurs in medieval records across Ireland. International visibility rose in the 20th century through Oona O'Neill (later Chaplin) and her granddaughter, actor Oona Chaplin. Today Oona feels both old-world and modern: concise, vowel-rich, and culturally versatile, with Úna, Una, and Oonagh as enduring variants.
