Juggling is a skill involving moving objects for entertainment or sport. The most recognizable form of juggling is toss juggling, in which the juggler throws objects up to catch and toss up again. Jugglers often refer to the objects they juggle as props. The most common props are balls or beanbags, rings, clubs, and special bounce balls. Some performers use more dramatic objects such as knives, fire torches, and even chainsaws. The term juggling can also refer to other prop-based skills such as diabolo, devil sticks, poi, cigar boxes, fire-dancing, contact juggling, hooping, foot bag and hat manipulation.
The word juggling derives from the Middle English jogelen (to entertain by performing tricks), in turn from the Old French jangler. There is also the Late Latin form joculare of Latin joculari, meaning to jest "Juggling" may be used metaphorically, like "multi-tasking," to mean constantly refocusing attention among responsibilities, such as in the title of the PBS documentary Juggling Work and Family.
