Although they share the same rule, what's the main difference between a "soccer" and a "football?" Why would they have a different name?

The difference between the name "football" and "soccer" depends on where you are! This is because America has another game called "football," also known as gridiron, where they play with an oval-shaped ball. So in America, they call this sport "soccer" to differentiate between the two. It's considered British English to call this game "football" instead of "soccer." Ex: In England, we don't play soccer. We play football. Ex: American football is so intense.
