And one of the most important places which English has changed is the playground! These playgrounds can be any place where the young people meet, such like a sports field or a beach. Often words using by black kids in big cities become popular for other kids many years later. On the beaches of southern California, teenagers invented words to describe what they felt when they surfed. These words found its way into the high schools and then to other places.
