Eilish (English)

Where does "Eilish" come from?

The English female given name 'Eilish' is borrowed from Irish 'Eilís'[1]. That Irish form traces back to French 'Élise', which functions as a clipping of 'Élisabeth'[2], a name ultimately rooted in Biblical Hebrew 'אלישבע' meaning 'my God is an oath'[4].
