"Blend of Gian and Carlos"
The name Giancarlos is commonly a male name from the "Spanish" origin.
Giancarlos is a compound masculine name that joins Gian, an Italian short form of Giovanni, with Carlos, the Spanish and Portuguese form of Charles. This double-name pattern, an Italian-leaning first element followed by a Spanish given name, is used in Spanish-speaking countries. The name first appears in United States birth records in 1988.
The pronunciation of Giancarlos is jahn-KAR-lohs.
