"Blend of De- and Michael"
The name Demichael is commonly a male name from the "American" origin.
Demichael is a modern American formation that joins the prefix De- to the established given name Michael. The same De- prefix appears in other twentieth-century American coinages such as DeShawn, DeAndre and DeMarcus, where it is attached to an existing name rather than carrying a meaning of its own. The name first appears in United States birth records in 1975, which fits that pattern of modern coinage rather than an inherited traditional name.
The pronunciation of Demichael is dee-MY-kul.
