"Blend of Ka and Shawn"
The name Kashawn is commonly a male name from the "American" origin.
Kashawn first appears in United States birth records in 1973 and carries no recorded meaning. Its form matches the American pattern in which a prefix is attached to Shawn, the anglicized spelling of Irish Sean, as in Keshawn, DeShawn and LaShawn. The Ka element functions as a name prefix in these formations rather than as a word with a meaning of its own.
The pronunciation of Kashawn is kuh-SHAWN.
