Lord

Lord - a deferential appellation for a person or deity who has authority, control, or power over others; a master, chief, or ruler. In only a few cases is "lord" a substantive title in itself, most commonly that of the Lord of the Manor and certain vestigial titles from the age of feudalism such as Lord of Mann, in other cases it is a generic term applied, for example, to persons who hold a title of the peerage or persons entitled to courtesy titles, or to refer to a group or body of peers.
