"Blend of La- and Darius"
The name Ladarrius is commonly a male name from the "American" origin.
Ladarrius belongs to a group of modern American names built with the prefix La-, alongside forms such as Ladarius, LaShawn and LaTonya, attached to an existing given name. Here the second element is Darius, the English form of the Old Persian royal name. The name's first appearance in United States birth records in 1978 fits this modern pattern rather than an older naming tradition.
The pronunciation of Ladarrius is luh-DAR-ee-us.
