A lollipop is hard candy on a stick that you lick or suck. You may suck on a lollipop and be surprised to find candy or gum in its center. Bonus!
Some lollipops are small, round, and fruity, while others are swirls of color as big as your head. Still other lollipops are long and skinny, or filled with liquid or bubble gum centers. The thing they all have in common is the stick you hold while eating them. Guesses about the origin of the lolli or lolly part of this word include to loll, or "dangle" the tongue, or the north England dialect "tongue" meaning of lolly.
