Rayna is a unique girl’s name that has roots in several languages and cultures. When Scandinavian in origin, it means “counsel” or “song.” But Rayna is also a Bulgarian derivation of the Latin name Regina, which means “queen,” and Radko, which means "happy." Regina is the feminine version of Rex, which means “king,” and makes Rayna a particularly illustrious name for baby. Finally, Rayna means “pure” and “holy” in Yiddish. Whether you’re planning to raise baby in faith or just as a little queen in their own right, this name will no doubt resonate deeply.
