Addy

Addy is a diminutive form of Germanic names beginning with the element adal, meaning noble, most commonly serving as a short form of Adelaide, Adeline, or Addison. Adelaide itself derives from the Old High German Adalheidis, combining adal with heid, meaning kind or type, giving the full sense of noble kind. The name gained widespread use in English-speaking countries during the nineteenth century, partly through the popularity of Queen Adelaide, consort of King William IV of Britain. Related forms include Addie, Ada, and Adela.
