Origin & History of “baron”

The earliest historical sense of baron, ‘tenant under the feudal system who held his land and title directly from the king’, can be traced back to its probable source, medieval Latin barō, which originally meant simply ‘man’, and hence ‘vassal’ or ‘retainer’. The word was of course brought into English by the Normans, as Anglo-Norman barun, and from earliest times was used as a title for someone belonging to the lowest order of peerage. some have suggested an ultimate Germanic origin, and compared Old high German baro ‘freeman’.
