juggler (n.)

c. 1100, iugulere "jester, buffoon," also "wizard, sorcerer," from Old English geogelere "magician, conjurer," also from Anglo-French jogelour, Old French jogleor (accusative), from Latin ioculatorem (nominative ioculator) "joker," from ioculari "to joke, to jest" (see jocular). The connecting notion between "magician" and "juggler" is dexterity. Especial sense "one who practices sleight of hand, one who performs tricks of dexterity" is from c. 1600.
