Did you know?

Piggyback was first used in the 16th century as an adverb, meaning "up on the back and shoulders" (as in "the child was carried piggyback"). It comes from a phrase of unknown origin, a pick pack. There is also the less-common adverb pickaback. The verb piggyback didn't piggyback on the adverb until the 19th century.
