The short answer
Isabel is a feminine name used in Spanish, Portuguese, English, French, German and Dutch. Behind the Name describes it as the medieval Occitan form of Elizabeth, which comes from the Hebrew name ʾElishevaʿ, "my God is an oath", from ʾel (referring to the Hebrew God) and shavaʿ ("oath"). The name spread through Spain, Portugal and France and was common among royalty by the 12th century; it grew popular in England in the 13th century after Isabella of Angoulême married King John. In Spain and Portugal it is the usual form of Elizabeth, whereas elsewhere it is treated as a parallel name. It is pronounced IZ-ə-bel in English and ee-sa-BEL in Spanish. In the United States it ranked #177 for girls in 2025.
Meaning and etymology
Behind the Name gives Isabel as the "medieval Occitan form of Elizabeth", with the root line "ʾel + shavaʿ". The Elizabeth entry supplies the gloss: the name comes "from Ἐλισάβετ (Elisabet), the Greek form of the Hebrew name אֱלִישֶׁבַע (ʾElishevaʿ) meaning 'my God is an oath', derived from the roots אֵל (ʾel) referring to the Hebrew God and שָׁבַע (shavaʿ) meaning 'oath'". Behind the Name's account of the name's spread is royal: it "spread throughout Spain, Portugal and France, becoming common among the royalty by the 12th century", grew popular in England in the 13th century after Isabella of Angoulême married King John, and was bolstered when Isabella of France married Edward II the following century. The entry adds that Isabel "is the usual form of the name Elizabeth in Spain and Portugal, though elsewhere it is considered a parallel name", as in France, where it stands alongside Élisabeth, and that it was borne by two Spanish ruling queens, including Isabel of Castile, who sponsored the explorations of Christopher Columbus. Behind the Name keeps a separate entry for the Occitan spelling Isabèl under 'Same Spelling'.
