Eilish

Eilish is a feminine given name of Irish origin. It is an Anglicized form of Éilis, the Irish equivalent of Elizabeth, which ultimately derives from the Hebrew Elisheba, meaning “God is my oath” or “God is my abundance.” In Ireland, Éilis and its variants have long been used in Gaelic contexts, and the spelling Eilish has become a popular English-language form in recent decades. In English-speaking settings, Eilish is commonly pronounced EE-lish, while in Irish usage the corresponding Gaelic form Éilis is typically pronounced roughly AY-lish.

Variants include Éilis, Eilis, and Eilís, among others, with Eilish serving as a modern Anglicization. The name is most strongly associated with Irish heritage and is found among the Irish diaspora in Britain, North America, and beyond. Usage has grown in line with broader interest in Gaelic names during the late 20th and early 21st centuries.

Beyond Ireland, the name appears in Irish communities worldwide and in modern media as a distinct given name rather than a direct translation of Elizabeth. Because Éilis is the traditional Gaelic form, Eilish and its variants are often chosen to emphasize Irish identity or heritage.

Related names include Éilis and Eilis, while Elizabeth remains the root form of the family of names from which Eilish is derived.
