Origin of the baby name Isabelle
Isabelle is the French and Dutch form of Isabel, which itself descended from the medieval reshaping of Elisabeth. The chain runs from Hebrew Elisheba through Greek and Latin, through the Iberian Isabel, and into French as Isabelle, a form that spread widely through courtly and religious culture across Europe. Like its Spanish counterpart, Isabelle carries the meaning my God is an oath or consecrated to God, a meaning as weighty as its sound is light.
