Isabelle

Isabelle is a French form of Isabel, itself a medieval Iberian adaptation of Elisabeth, the Latin and Greek rendering of the Hebrew name Elisheba, meaning something along the lines of my God is an oath or my God is abundance. The name spread widely through medieval Europe, carried in part by figures such as Isabelle of France, the thirteenth-century princess and saint. Closely related forms include Isabella, Isabel, Elisabeth, and Elizabeth, which share the same Hebrew root across different linguistic traditions.
