Etymology of football

While it is widely assumed that the word "football" (or "foot ball") references the action of the foot kicking a ball, there is a historical explanation, which is that football originally referred to a variety of games in medieval Europe, which were played on foot. These games were usually played by peasants, as opposed to the horse-riding sports (such as polo) often played by aristocrats. There is no conclusive evidence for either explanation, and the word football has always implied a variety of games played on foot, not just those that involved kicking a ball. In some cases, the word football has even been applied to games which have specifically outlawed kicking the ball.
