"Blend of Maria and Fernanda"
The name Marifer is commonly a female name from the "Spanish" origin.
Marifer is a Spanish-language compound name formed from the two established given names Maria and Fernanda, usually as a shortened form of Maria Fernanda. Both elements are standard Spanish names, and the combination is used as a name in its own right in Spanish-speaking countries. The shortening pattern, keeping the opening of each element, is the same one seen in other Spanish double names.
The pronunciation of Marifer is mah-ree-FEHR.
