'Elise' originates from Old French and German, ultimately from Hebrew; specifically from the Hebrew name 'Elisheva', where 'Elisheva' meant 'God is my oath'.

'Elise' changed from the Hebrew name 'Elisheva' to Greek/Latin forms like 'Elisabet'/'Elisabeth', then to Old French and German short forms (e.g. 'Élise'), and eventually became the modern English given name 'Elise'.

Initially it meant 'God is my oath' as a form of the Hebrew name; over time it evolved into a shorter, independent given name 'Elise' while retaining its link to 'Elisabeth'.
