Meaning and origin of Casper
Casper is a Dutch and Persian name that is usually said to mean “treasurer”.
Casper is the Dutch and Scandinavian form of Jasper, a name traditionally given to one of the three Magi who visited the infant Jesus. The Magi's names come from later Christian tradition rather than the Bible itself, and Jasper is often traced to a Persian word meaning treasurer, though that link is not entirely certain. The German painter Caspar David Friedrich bore a closely related spelling. Many people also know the name from Casper the Friendly Ghost, the cartoon character. Casper has a gentle, playful feel, and Cas is a handy nickname for this light and friendly choice.
Other spellings with the same sound: Kasper, Caspar.
