Relative rank that an individual holds, with attendant rights, duties, and lifestyle, in a social hierarchy based on honour and prestige. Status is often ascribed on the basis of sex, age, family relationships, and birth, placing one into a particular social group irrespective of ability or accomplishments. Achieved status, on the other hand, is based on educational attainment, occupational choice, marital status, and other factors involving personal effort. Status groups differ from social classes in being based on considerations of honour and prestige rather than purely economic position. Relative status is a major determinant of people's behaviour toward one another, and competition for status seems to be a prime human motivator.

Any of the five positions of the feet fundamental to all classical ballet. First codified by Pierre Beauchamp (1636–1705) in 1680, the positions form the base from which a dancer achieves stability or aplomb, the basic law of ballet. Fundamental to all the positions is the turnout, or rotation of the dancer's legs out from the hips, which creates a firm basis for movement in any direction. Various positions of the arms and hands (port de bras) complete the figures.
