Lucius

Lucius ( "Loukios"; ) is a male given name derived from "Lucius" (abbreviated "L."), one of the small group of common Latin forenames ("praenomina") found in the culture of ancient Rome. Lucius derives from Latin word "Lux" (gen. "lucis"), meaning "light" (<PIE "*leuk-" "brightness", Latin verb "lucere" "to shine"), and is a cognate of the name Lucas. Another etymology proposed is a derivation from Etruscan "Lauchum" (or "Lauchme") meaning "king", which however was transferred into Latin as "Lucumo". Lucy is the feminine derivative of the name.
In addition, Lucius is a British masculine given name and an Austrian, German, Luxembourgish and Dutch surname. Lucius has been translated into Italian, Spanish and Portuguese, as Lucio. Derived from the related patronymic "Lucianus" is "Luciano" in Italian, Spanish and Portuguese and "Lucien" in French.
