In ancient Rome, the emperor's palace was located on the Palatine Hill, known as "Palatium" in Latin. Since the site was the seat of imperial power, the word "palatium" came to mean "imperial" and later "imperial official." Different forms of the word passed through Latin, Italian, and French, picking up various meanings along the way, until eventually some of those forms made their way into English. "Paladin" is one of the etymological heirs of "palatium"; another descendant is the word "palace."
