"Variant of DeShawn"
The name Deshun is commonly a male name from the "American" origin.
Deshun is a modern American name built on the De- prefix seen in names such as DeShawn, DeAndre and DeMarco, joined to the name Shawn. The spelling shun represents the same sound as Shawn, so Deshun is best described as a spelling variant of DeShawn rather than as a name with an older root in another language. It first appears in United States birth records in 1969.
DeShawn means "God is gracious. A form of Shaun.".
The pronunciation of Deshun is duh-SHUN.
