Lord is traditionally an 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 formal title in itself, most commonly that of Lord of the Manor (now largely historical) and certain other vestigial titles from the age of feudalism such as Lord of Mann. More generally, Lord is a generic term applied, for example, to people who hold a title of the peerage in the United Kingdom, or are entitled to courtesy titles, or to refer to a group or body of peers.
