Final answer:
In dance, a 'caper' is a quick, lively step that involves the beating of legs, representing playfulness and technical skill.
Step-by-step explanation:
In the field of dance, the term caper refers to a quick, lively step with beating legs. This type of movement is characteristic of many dance forms and can be a display of both the dancer's technical skill and their ability to express joy or playfulness through movement.
Unlike a graceful spin or a slow and controlled motion, a caper is typically a more energetic and buoyant action, and though it might sometimes involve a jump, it is specifically noted for the vigorous leg action.
