Composed of the roots aud- (wealth) and -wakar (awake), it may be translated "warden of riches" or "watchman of property" and is a kenning for lord.[1] The name is attested in many variations. The first root may appear as Aut-, Ad-, Ud-, Od-, Ot- or Oth- and is attested as a name on its own, Aud, in the 3rd century AD. The name Otto is a derivative.[2]
The medieval German form was Ottokar, whence the Czech form Otakar. The Czech name Žiroslav (Polish Żyrosław) has the same meaning. The Greek name Plutarch also means "lord of wealth".[1]
