"Blend of Maria and Clara"
The name Mariaclara is commonly a female name.
Mariaclara joins two established given names, Maria and Clara. Clara goes back to the Latin clarus, meaning bright or clear, and Maria is the Latin and Romance form of the name of Mary. The same pair appears as Mariachiara in Italian and Maria Clara in Spanish and Portuguese use, so the single-word spelling is a joining of the two elements rather than a separate name with its own root.
The pronunciation of Mariaclara is muh-REE-uh-KLAIR-uh.
