balloon

Origin

First use appears c. 1591, "a game played with a large, inflated leather ball" (possibly via Middle French ballon) from Italian pallone (“large ball”) from palla (“ball”), from Lombardic *palla. The Northern Italian form, balla (“ball-shaped bundle”), today a doublet, likely derived from Old French balle, from Frankish *balla (“ball”), and may have influenced the spelling of this word. Both Germanic words are from Proto-Germanic *ballô (“ball”), *balluz, from Proto-Indo-European *bʰoln- (“bubble”), from Proto-Indo-European *bʰel- (“to blow, swell, inflate”). Akin to Old High German ballo, bal (“ball”), (German Ballen (“bale”); Ball "ball"). Doublet of ballon. More at ball.
