Ivi is a relatively rare name in the United States, but it’s gaining traction as a modern and distinctive choice, primarily for girls. It finds greater popularity in Estonia and Eastern Europe, where it’s a recognized traditional name. The name’s origins are linked to Slavic names like Ivanka and Ivana, ultimately stemming from the Hebrew Yochanan.
