what is the difference between a knight and a lord
Lord 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.
Knights Who Say Ni The head knight acknowledges that "it is a good shrubbery", but asserts that the knights cannot allow Arthur and his followers to pass through the wood because they are no longer the Knights who say "Ni!" They are now the Knights who say "Ekke Ekke Ekke Ekke Ptang Zoo Boing!"[i] and must therefore give Arthur a test. Unable to pronounce the new name, Arthur addresses them as "Knights who until recently said 'Ni!'," inquiring as to the nature of the test. The head knight demands another shrubbery, to be placed next to but slightly higher than the first; and then Arthur "must cut down the mightiest tree in the forestâ€”with a herring!" The knight presents a herring to be used. Arthur objects, asserting that "it can't be done!" upon which the knights recoil as though in fear and pain. It soon emerges that the knights are unable to withstand the word "it", which Arthur's party is unable to avoid saying. The knights are soon incapacitated by the word, which even the head knight cannot stop repeating, allowing Arthur and his followers to make their escape.[1]
