Feminine form of Cyril, from Greek kyrios meaning "lord" or "master."
Cyrilla is the elegant feminine form of Cyril, a name of profound historical weight. Cyril derives from the Greek *Kyrillos*, itself thought to come from *kyrios*, meaning "lord" or "master." The name's enduring fame rests almost entirely on one man: Saint Cyril of Thessalonica (826–869 AD), a Byzantine scholar and missionary who, together with his brother Methodius, created the Glagolitic alphabet to transcribe the Slavic languages — the ancestor of the Cyrillic script still used across Russia, Bulgaria, Serbia, and much of Eastern Europe today.
Few names can claim to have literally shaped how hundreds of millions of people write. Cyrilla, as the feminine counterpart, carries all of that scholarly and sacred gravity with an added flourish. There was also a Saint Cyrilla of Cyrene, an early Christian martyr of the third century, which cemented the name's place in Christian hagiography.
In medieval Europe, the name appeared sporadically in noble and religious circles, valued for its association with learning and devotion. Its Latinate feminine ending gives it a formal, almost ceremonial feel — a name suited to proclamation. In modern usage, Cyrilla is exceptionally rare outside Eastern European communities, which grants it a kind of quiet distinction.
It is a name for those who appreciate depth over fashion — it asks to be looked up, to be explained, to open a conversation about alphabets and medieval missionaries and the strange power of written language. For parents drawn to unusual classical names with genuine historical substance, Cyrilla offers something genuinely rare: obscurity with a story worth telling.
