Knight is the English term for a social position originating in the Midle Ages. In the Commonwealth of Nations, knighthood is a non-heritable form of gentry. Elsewhere, the Spanish Caballero (related to "chivalry"), the Italian Cavaliere, the German Ritter (related to the English word "Rider" and the Swedish word Riddare), or the Polish Kawaler (for Modern Era knighthoods or Rycerz for medieval knighthoods) are commonly used in Continental Europe. Outside the British Commonwealth, the title is respected but may carry less significance, and thus may or may not appear, for example, in the mass media and other publications. There are technically differing levels of knighthood (see Order of the British Empire), but in practice these are even more symbolic than the title itself today and thus only express the greatness of the recipient's achievements in the eyes of the Crown.
