"Blend of Maria and Isabel"
The name Mariaisabel is commonly a female name.
Mariaisabel joins two established given names, Maria and Isabel, written as one word. In Spanish and Portuguese naming, a child may be given both names together, normally written with a space as Maria Isabel; the joined spelling appears in United States birth records from 1970. The elements are the same in either spelling.
The pronunciation of Mariaisabel is muh-REE-uh-IZ-uh-bel.
