From French ballon, from Middle French ballon, from Italian pallone (“large ball”), from palla (“ball”), from Lombardic *palla (“ball”), although the then Northern Italian form balla, from Old French balle, from Frankish balla, is likely the more direct influence; both from Proto-Germanic *ballô (“ball”), *balluz, from Proto-Indo-European *bholn- (“bubble”), from Proto-Indo-European *bhel- (“to blow, swell, inflate”).
