Adelaide

Adelaide is a feminine name of Old High German origin, derived from the elements adal, meaning noble, and heid, meaning kind or type, giving the overall sense of noble natured. It was borne notably by Saint Adelaide of Italy, the tenth-century empress and wife of Otto I, whose widespread veneration helped popularize the name across medieval Europe. The French form Adélaïde gained renewed prominence through the French royal family in the eighteenth and nineteenth centuries. Closely related forms include Ada, Adeline, Alice, and Heidi, all sharing roots in the same Germanic elements.
