Origin & History of “platoon”
Platoon means etymologically ‘little ball’. It comes from French peloton, a diminutive form of pelote ‘ball’ (source of English pellet). The notion of a ‘small ball’ was extended in French to a ‘little cluster of people or group of soldiers’ – hence the meaning of English platoon.
