A juggler is someone who can toss and catch several objects at once, always keeping at least one of them in the air at any given moment. If you want to become a juggler, try juggling tennis balls instead of fiery torches.
Watching a juggler perform can be awe-inspiring, especially if she's juggling knives or some other dangerous set of objects. You can become a juggler simply by learning to juggle, and professional jugglers can work for circuses or perform for money at festivals and street fairs. Juggler, jester, and wizard all once shared a meaning as well as a root, the Old English geogelere, "magician or conjurer."
