Addy

Addy is an English diminutive form with medieval roots, derived as a short form of names beginning with Ad-, most commonly Adelaide, Adeline, or Adam. Adelaide traces back to the Old High German name Adalheidis, composed of the elements adal, meaning noble, and heid, meaning kind or sort, while Adam comes from the Hebrew name meaning man or earth. Addy has functioned as both a feminine and masculine pet name throughout English history, reflecting the range of longer names it can represent. Related forms include Addie, Ada, and Dell.
