<P> Lord is an appellation for a person or deity who has authority, control, or power over others acting like a master, a chief, or a ruler . The appellation can also denote certain persons who hold a title of the peerage in the United Kingdom, or are entitled to courtesy titles . The collective "Lords" can refer to a group or body of peers . </P> <P> According to the Oxford Dictionary of English, the etymology of the word can be traced back to the Old English word hlāford which originated from hlāfweard meaning "loaf - ward" or "bread keeper", reflecting the Germanic tribal custom of a chieftain providing food for his followers . The appellation "lord" is primarily applied to men, while for women the appellation "lady" is used . However, this is no longer universal: the Lord of Mann, a title currently held by the Queen of the United Kingdom, and female Lord Mayors are examples of women who are styled Lord . </P> <P> Under the feudal system, "lord" had a wide, loose and varied meaning . An overlord was a person from whom a landholding or a manor was held by a mesne lord or vassal under various forms of feudal land tenure . The modern term "landlord" is a vestigial survival of this function . A liege lord was a person to whom a vassal owed sworn allegiance . Neither of these terms were titular dignities, but rather factual appellations, which described the relationship between two or more persons within the highly stratified feudal social system . For example, a man might be Lord of the Manor to his own tenants but also a vassal of his own overlord, who in turn was a vassal of the King . Where a knight was a lord of the manor, he was referred to in contemporary documents as "John (Surname), knight, lord of (manor name)". A feudal baron was a true titular dignity, with the right to attend Parliament, but a feudal baron, Lord of the Manor of many manors, was a vassal of the King . </P> <P> The substantive title of "Lord of the Manor" came into use in the English medieval system of feudalism after the Norman Conquest of 1066 . The title "Lord of the Manor" was a titular feudal dignity which derived its force from the existence and operation of a manorial court or court baron at which he or his steward presided . To the tenants of a manor their lord was a man who commanded on occasion the power of exercising capital punishment over them . The term invariably used in contemporary mediaeval documents is simply "lord of X", X being the name of the manor . The term "Lord of the Manor" is a recent usage of historians to distinguish such lords from feudal barons and other powerful persons referred to in ancient documents variously as "Sire" (mediaeval French), "Dominus" (Latin), "Lord" etc . The title of "Lord of the Manor" is recognised by the British Government, in the form of the Her Majesty's Land Registry, as one of three elements of a manor that can affect Land Registry . Modern legal cases have been won by persons claiming rights as lords of the manor over village greens . The heads of many ancient English land - owning families have continued to be lords of the manor of lands they have inherited . </P>
