Meaning and origin of Cyril
Cyril is a Greek name that means “lordly”.
Cyril comes from Greek Kyrillos, from kyrios, lord. It was borne by several important saints, including Cyril of Alexandria, a fifth-century theologian, and Cyril, the ninth-century missionary to the Slavs who, with his brother Methodius, created an early Slavic alphabet. The Cyrillic script used for Russian and other languages is named after him. In English the name is said SEER-ul or SIR-ul. It was a traditional British name in the early twentieth century and has a distinctly vintage feel today. Kirill is the Russian form, and Cyrille the French.
