Kyrillos (Greek Κύριλλος) derives from kyrios “lord, master,” with the -illos diminutive/affectional ending, yielding the sense “lordly,” “of the Lord,” or “belonging to a master.” It arose in late antique Greek and passed into ecclesiastical Latin as Cyrillus, giving English Cyril. The name’s sacred resonance made it favored in Christian communities, especially Greek and Coptic.

It was borne by influential saints and churchmen: Cyril of Jerusalem, Cyril of Alexandria, and Saint Cyril of Thessalonica, co‑apostle of the Slavs, ensuring wide medieval spread. Multiple patriarchs and popes of Alexandria have been titled Kyrillos (notably the 20th‑century Coptic Pope Kyrillos VI). Variants and cognates include Cyril (English), Cyrille/Cyrillus (French/Latin), Kirill (Russian), Kyrylo (Ukrainian), Kiril (Bulgarian/Macedonian), Kirilo (Serbian), Cyryl (Polish), Cirilo (Spanish/Portuguese), and Kirillos/Kyrellos in Arabic‑speaking Coptic usage. The name remains familiar in Greece, Cyprus, and across Eastern Christian traditions.
