"Blend of Jer and Michael"
The name Jermichael is commonly a male name from the "American" origin.
Jermichael is a modern American formation built from the short element Jer, as seen in names such as Jerry and Jeremy, followed by Michael. The first year it appears in US birth records is 1974, which fits a coined or blended name rather than one inherited from an older naming tradition. The same pattern appears in other American names that attach a short first element to a full given name.
The pronunciation of Jermichael is jer-MY-kul.
