Isabelle

Isabelle is a French and Medieval Latin form of Elizabeth, ultimately derived from the Hebrew name Elisheba, meaning something along the lines of my God is an oath or my God is abundance. The name reached Western Europe through Spanish and Occitan forms of the Hebrew original, becoming widely adopted in France and the broader Romance-speaking world during the medieval period. Isabelle of France, the daughter of Philip IV and queen consort of England, is among its most prominent historical bearers. Closely related forms include Isabel, Isabella, Elisabeth, and Izabelle.
