Kyrylo

Kyrylo comes from the Greek Kyrillos, built on kyrios, meaning "lord, master." The Ukrainian form keeps that root close. Say it in Polish and the sense arrives as "pan, władca," a grand title resting on a young boy.

The most famous bearer stands behind an alphabet. Saint Cyril, working with his brother Methodius in the ninth century, shaped a written script for the Slavic tongue, and Cyrillic still bears his name. Kyrylo is the Ukrainian route to that same saint, and it has traveled with Ukrainian families for generations.

On a Polish class register, the name marks a household with roots to the east. There are no soft diminutives waiting behind it, no second form to hide in. What the boy answers to is simply Kyrylo, a name whose old Greek core means lord and master.
