What Sergiu means
Where Sergiu comes from and what it has meant to the people who carry it.
Sergiu comes from the Latin family name Sergius, borne by an old Roman clan, the gens Sergia. One of its members was Lucius Sergius Catilina, the conspirator Cicero denounced. The plain meaning handed down for the name is servant, in Polish sługa. That sense of service was attached to the name later, since the Roman surname itself has no settled translation.
Sergiu is the Romanian shape of the same root that Polish knows as Sergiusz. It moved through the Latin-speaking world and into the eastern reaches of Europe, where it settled among Orthodox and Catholic families alike. Early Christians carried a version of it too. Saint Sergius, a Roman soldier martyred with his companion Bacchus, gave the name a place on the church calendar.
A boy called Sergiu today might hear his name read from a class register beside more common Polish forms. The meaning underneath stays the same. To answer to Sergiu is to answer to a word that once meant servant, sługa in Polish, rooted in Latin Sergius.
