booty: [15] Booty has no connection with boots. It came into English as butin (it did not finally lose its n until the 18th century), a borrowing from Old French butin, but Old French had got it from Middle Low German būte ‘exchange’ (whence German beute and Dutch buit ‘loot’), pointing to a prehistoric Germanic source *būtiōn. => filibuster, freebooter[booty etymology, booty origin, 英语词源]
