Ioannis

Ioannis is the Modern Greek form of the ancient name Ioannes, itself derived from the Hebrew Yohanan, meaning God is gracious. The name entered Greek through the New Testament, where it was borne by several important figures including John the Baptist and the apostle John. Its enduring popularity across the Christian world gave rise to a vast family of cognates and variants, including Yannis, Giannis, John, Giovanni, Juan, Jean, and Ivan.
