Feminine short form of Edward, from Old English 'ēad' (wealth) and 'weard' (guardian).
Edwa is a feminine short form of Edward, the Old English name built from ead, meaning wealth, and weard, meaning guardian. That makes the name part of one of the most enduring clusters in English royal and classic naming.
Even in shortened form, Edwa still carries the sense of protection joined to prosperity. As a name, Edwa feels spare, unusual, and slightly antique, with the charm of an older form that has been trimmed down to something more direct. It is not common in contemporary use, but that rarity gives it a memorable simplicity. The name retains Edward's historical backbone while taking on a softer and more compact feminine profile.
