Isabel

Traditionally “my God is an oath”, through Elizabeth.

Isabel is a feminine name in the Elizabeth family, carrying the traditional Hebrew meaning “my God is an oath”. The form Isabel is established in Spanish and Portuguese. In Spanish, the emphasis falls on the last syllable, I-sa-BEL; the English pronunciation usually begins with the strongest beat, IZ-uh-bel. This is a useful distinction for a family using both languages: choosing the spelling does not necessarily choose a single pronunciation. Compared with the related forms Isabelle and Isabella, Isabel looks particularly uncluttered. The rounded middle and neat final l can give it an understated elegance, with enough shape to feel complete on its own. It may appeal if you enjoy the formality of Elizabeth but prefer a less elaborate written form.

Etymology: A form of Elizabeth established in Spanish and Portuguese, with an ultimate Hebrew root in Elisheba. Its medieval development is usually traced through Occitan.
