Soccer? Football? American Football?
People in the United States refer to the sport that you kick a ball into a goal, soccer.
Most people around the world call this sport football; however, the original name of soccer started in England.
The upper class in England called this sport soccer in the early days, but once the middle and lower class became interested they changed it to football.
The problem with switching soccer to football was that other countries such as United States, Canada, Ireland, Australia, New Zealand, South Africa, and others already had a game called football.
Now people refer to our "football" as "American football".
