Maddie

Maddie is a familiar short form of names including Madeline and Madison, and it is also used as a complete name. Madeline belongs to the Magdalene family, referring to a woman from Magdala. Madison has a separate surname history, so Maddie should not be given one combined meaning drawn from both routes.

Maddy is a nearby spelling with the same usual two-syllable sound. Parents who know they will use Maddie every day can choose it directly rather than assuming a longer official form is required. If it honors a relative, the particular longer name behind that person's nickname can supply the family story. The informal beginning does not make Maddie incomplete as an independent given name.
