Elsa

Elsa is a Germanic name that originated as a short form of Elisabeth, itself derived from the Hebrew Elisheba, meaning God is my oath or God is abundance. It gained widespread use across Scandinavia and central Europe as an independent name during the nineteenth century, carried in part by its appearance in Richard Wagner's opera Lohengrin, where Elsa of Brabant is the heroine. The name received renewed global prominence through the Disney film Frozen. Closely related forms include Else, Elise, and Lisa.
