"Blend of Da and John"
The name Dajohn is commonly a male name from the "American" origin.
Dajohn is a modern American formation rather than an inherited traditional name. It attaches the prefix Da-, which also appears in other American coinages such as Daquan and Dashawn, to the established given name John. Its first appearance in United States birth records in 1991 is consistent with that kind of late twentieth-century coinage.
The pronunciation of Dajohn is duh-JAHN.
