Elsa

Elsa is a short form of Elisabeth, which derives from the Hebrew name Elisheba, composed of the elements el, meaning God, and sheva, meaning oath or perhaps seven. The name has long been used across Germanic and Scandinavian languages, gaining literary prominence through the character Elsa in Richard Wagner's 1850 opera Lohengrin. It spread further into English and Romance languages over the nineteenth and twentieth centuries, receiving a major boost in popular culture from the 2013 Disney film Frozen. Related forms include Else, Elise, and Elisabeth itself.
