Soccer is a sport that's played with a round black and white ball that players pass to each other using their feet. To win a soccer match, your side has to kick the ball into the goal more times than your rivals do. Go team!
In most parts of the world, soccer is known as football, which makes sense since players (except the goalie) can't touch the ball with their hands — they mainly control and move it with their feet. In the U.S., however, football is a completely different sport, one that's known as American football everywhere else,. Soccer comes from socca, slang for Assoc., which is a shortened version of Association football.
