Meaning & History
Eilish is an Anglicized form of Eilís, the Irish Gaelic variation of Elizabeth (or sometimes Alice). The name traces its roots back to the Hebrew אֱלִישֶׁבַע (ʾElishevaʿ), meaning "my God is an oath," derived from אֵל (ʾel) for God and שָׁבַע (shavaʿ) for "oath." In the Old Testament, Elisheba appears as the wife of Aaron, while the Greek form Elizabeth is the mother of John the Baptist in the New Testament.
Pronounced either AY-lish or EYE-lish, Eilish (also spelled Eylish) is strictly an Irish given name. It began as an Anglicization of Éilis and Éilís, the native Irish forms that diverged from the continental Elizabeth under the influence of the Gaelic language. While Elizabeth has been a perennial favorite in England since the reign of Queen Elizabeth I, the Irish form remained distinct and was primarily used within Ireland and among the Irish diaspora.
Notable Bearers
The name appears most famously in modern pop culture through Billie Eilish Pirate Baird O'Connell, the American singer-songwriter known simply as Billie Eilish. She adopted Eilish as her stage surname, elevating the name's global recognition. Before her, notable bearers included Irish politician Eilish Collins Main, Scottish athlete Eilish McColgan (a middle-distance runner), and Irish authors Eilís Dillon and Éilís Ní Dhuibhne. Another poignant bearer was Eilish Holton, an Irish girl famous for being a conjoined twin whose sister Katie did not survive their separation surgery.
Linguistic and Cultural Context
Eilish is part of a broader tradition where Irish named are anglicized to fit English orthography while retaining their Gaelic pronunciation. Related forms of Elizabeth across languages include Zabel (Armenian), Elixabete (Basque), Elisheba (Biblical), Elisabeth (Swedish), and Elisabet (Swedish).
