The name Isabel is a girl's name of Spanish origin meaning "pledged to God".
Isabel derived from Elizabeth in southwest Europe during the Middle Ages. It was originally written as Elisabel, but the first syllable was dropped as it spread across the continent. In Spain and Portugal, Isabel and Elizabeth are considered to be variations of the same name, but they are treated as separate names in other European countries and the US.
The charming Isabel is hugely fashionable again, a century after its first wave of success. And it's easy to see why: it's ladylike (a la Isabel Archer in Henry James's Portrait of a Lady) and melodic, traditional yet slightly offbeat. Isabel sounds smart as well as pretty.
Two noted cultural namesakes are Chilean author Isabel Allende and painter Isabel Bishop, as well as Cuban-American fashion designer Isabel Toledo.
The only downside: with Isabella's recent popularity, there are so many other little Isabels, Isabelles, Isabellas, Belles, and Bellas, yours would be far from unique.
The Office's Angela Kinsley named her baby girl Isabel, and Annette Bening and Warren Beatty have a teen-aged Isabel.
Isabelle is the French version, Isabella the Italian one, and Isobel the Scottish spelling, which has a definite character of her own, the 'o' giving her an extra infusion of strength.
Nifty nicknames include Izzy, Ibby, Isa and Belle.
