Beatriz is the Spanish and Portuguese form of Beatrice — from the Latin beatrix, meaning "bringer of joy" or "she who blesses." The same root gives the English "beatitude."
Beatriz is one of the most popular girl's names across the Spanish- and Portuguese-speaking world. In Italian literature, Beatrice was Dante's beloved muse in The Divine Comedy (her name spelled Beatrice in the original).
Beatriz reduces to nine — the number of brought joy.
