[ 3 syll. ei-lee(n), eil-e-en ] The baby girl name Eileen is pronounced as -ay-LIYIYN †. Eileen is used mostly in the English, Irish, and Gaelic languages. Its language of origin is Old French and Old Greek. Old French origin, English and Irish use: It is derived from the words 'aveline' meaning hazelnut ; 'avis' bird. The name is Anglicized from the Gaelic name Aibhilin (Old Irish) or Eibhlín, from the omitted pronunciation of the Gaelic '-bh-'; in another pronunciation of '-bh-' as 'v' comes the name Evelyn. The Gaelic names are themselves from Aveline (Old French). Aveline is of uncertain origin; it could be from the Old French word for 'hazelnut', or the word 'avis', or it could be ultimately from a diminutive of Ava. The name Eileen was adopted by English speakers in the late 19th century through the influence of Irish migrants.
