"Blend of Na and Shaun"
The name Nashaun is commonly a male name from the "American" origin.
Nashaun is a modern American formation: an initial Na- element joined to Shaun, an English spelling of the Irish name Sean. It first appears in United States birth records in 1981, and no earlier use in another naming tradition is documented. The name therefore has no inherited meaning beyond that of its Shaun element, which corresponds to John.
The pronunciation of Nashaun is nuh-SHAWN.
