What Sergei means
Where Sergei comes from and what it has meant to the people who carry it.
Sergei belongs to the Slavic world, and in Russian it has traveled farthest of all. Polish keeps its own form, Sergiusz, while the shorter Sergei stays marked as Russian. The short meaning attached to the name is servant, sługa in Polish, a sense of one who attends and serves rather than one who rules.
That reading fits its most famous bearer. Sergius of Radonezh, the medieval monk who founded the Trinity Lavra near Moscow, became one of the patron saints of Russia. His life gave servant a plain meaning, the monk as one who serves God. Music claimed the name too. Sergei Rachmaninoff and Sergei Prokofiev carried it into concert halls far from any monastery.
In a Polish class register you meet Sergiusz more readily than Sergei. Both forms lead back to the same modest gloss, servant.
