It’s simple, really. The game we call football is called football because it’s derived from the English game called football. Confused? Thought soccer was what the English called football? It is… sort of. Soccer was the game called Association Football in England. The English got tired of saying Association Football, and just shortened it to football – only problem: there was already a game called football, so the English then changed the name of THAT to rugby. However, by that time, the Americans had already made football from football and saw no reason to change it. By the way, the Australians still call rugby football. See how easy that is to understand? 😉 😀
