"Variant of Edison"
The name Edinson is commonly a male name from the "English" origin.
Edinson is a variant of Edison, the surname of inventor Thomas Edison that became a given name in the Americas. The form with an inserted n is used in Spanish-speaking Latin America, where the Uruguayan footballer Edinson Cavani, born in 1987, is a documented bearer. Its first appearance in United States birth records in 1992 is consistent with that Latin American usage rather than with an independent coinage in the United States.
Edison means "Son of Edward|son of the wealthy friend".
The pronunciation of Edinson is ED-in-son.
