Adelaide

Adelaide is a Latinate form of the medieval Germanic name Adalheidis, composed of the elements adal, meaning noble, and heid, meaning kind or sort, giving an overall sense of noble nature. It was borne by several medieval queens and empresses, most notably Adelaide of Italy, a 10th-century Holy Roman Empress venerated as a saint, which helped spread the name across Europe. The name gained particular popularity in English-speaking countries during the 19th century, partly through association with Queen Adelaide, consort of King William IV of Britain. Related forms include Adélaïde in French, Ada, Adele, Adeline, Alice, and Heidi.
