Isabelle
/i.za.bɛl/
Isabelle is the French and German spelling variant of Isabel, derived ultimately from the Hebrew Elisheba meaning “My God is an oath.” It developed through the Old French and Occitan forms of Elizabeth and was established as a standard spelling in
continental Europe, particularly in France, Belgium, Switzerland, and Germany, by the medieval period.
The addition of the final “-le” distinguishes the French form from the Spanish Isabel and the Italian Isabella, while maintaining the same classical lineage.
