"Blend of Ty and Shawn"
The name Tyshon is commonly a male name from the "American" origin.
Tyshon belongs to a group of modern American names formed from the Ty- prefix, familiar from names such as Tyler and Tyrone, joined to Shawn; the -shon ending spells the same sound. The same pattern gives the related spellings Tyshawn and Tyshaun. This is a twentieth-century American construction rather than a name inherited from an older European or biblical tradition, and it has no meaning of its own beyond the elements it is built from.
The pronunciation of Tyshon is TY-shon.
