Sergius as a Baby Name. Meaning and Origin of Sergius

What is the meaning of the name Sergius ?

The baby name Sergius is a Male name , 3 syllables long and is pronounced /ˈsɜːrɡiəs/ (SER-jee-əs).

Sergius is Latin in Origin.

Sergius is the Latin gentilicium of the ancient Roman gens Sergia, most likely of Etruscan origin and therefore of uncertain meaning. Classical and later scholars sometimes connected it by folk etymology to the Latin verb servare “to guard,” yielding an interpretive sense of “protector/guardian,” though this is not etymologically secure. The rare feminine form is Sergia.

The name appears across Roman history (e.g., Lucius Sergius Catilina) and entered Christian onomastics through revered martyrs Sergius and Bacchus and several medieval popes. Its Eastern veneration, especially via St. Sergius of Radonezh, propelled widespread use in Slavic lands. Modern variants include Sergey/Sergei (Russian), Serhii/Serhiy (Ukrainian), Siarhei (Belarusian), Sergiu (Romanian), Sergio (Italian, Spanish), Sérgio (Portuguese), Serge (French), Sergi (Catalan), Sergej/Sergije (South Slavic), Sergejus (Lithuanian), Sergejs (Latvian), and Sergiusz (Polish). Diminutives and short forms include Serg, Serj, Seryozha (Russian), and Serginho (Portuguese).
