A step. Many of the common names of steps in ballet are adjectives (or
participles) instead of nouns; these names have the word "pas" understood: thus,
for example, "coupé" (which everybody says) is actually short for "pas coupé"
["cut step"] (which nobody says). Also used to refer to a dance, as pas de deux,
a dance for two; pas de quatre, a dance for four.
