palace: [13] The Palātium, or Mons Palātīnus (in English the ‘Palatine hill’), was one of the seven hills of ancient Rome. On it the emperor Augustus built a house, which in due course grew into a grand imperial palace, also called the Palātium. This came to be used as a generic term for such residences, and passed into English via Old French paleis. The derived Latin adjective palātīnus has given English paladin [16] and palatine [15]. => paladin, palatine[palace etymology, palace origin, 英语词源]
