Meaning and origin of Luiza
Luiza is a Portuguese and Germanic name that means “Portuguese form of Louisa, famous warrior”.
Luiza is the Portuguese form of Louisa, the feminine of Louis, from the Germanic Hludwig, famous warrior, from hlud, famous, and wig, war. It is common in Brazil and Portugal, and the same spelling is also used in Romania and Poland. In Portuguese it is said loo-EE-zuh, with the stress on the middle syllable and a z sound. Louisa, Luisa and Eloise are related names. Lu and Lulu are possible short forms. The Brazilian singer Luiza Possi is a known bearer. The z spelling signals the soft pronunciation, unlike Spanish Luisa, which uses an s sound.
