While it is widely believed that the word "football" (or "foot ball") originated in reference to the action of the foot kicking a ball, there is a rival explanation, which has it 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 often played by aristocrats. While there is no conclusive evidence for this explanation, 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. Be careful those yellow card, you have avoid them and kick the ball into the goal. Good luck!
