the.com/juggle

means To keep several objects, tasks, or responsibilities moving through the air (literal or metaphorical) at once, through practiced skill or frantic improvisation.

from From Old French 'jogler,' meaning to jest or perform tricks, which traces back to Latin 'joculari' — to joke — itself from 'joculus,' a little jest, diminutive of 'jocus' (joke). The word originally described any performer of comic or deceptive tricks, not just ball-tossing — medieval jugglers were closer to jesters and conjurers than circus acts. The narrower sense of keeping objects airborne came later, as that particular trick became the signature act of the trade.
