Who decides how English is spoken around the world? Do teachers in the colleges and schools? What about those who write dictionaries or books? Do they decide what is good and what is bad English? Or do governments decide when a language will change? Probably you have thought about this question once or twice before. The answer is that none of these people decide how English will be spoken. Believe it or not, many of the biggest changes in how English is spoken have come from common people in the streets. And one of the most important places where English has changed is on the playground! These playground can be any place where young people meet, such as a sports field or a beach. For example, black kids invented many new words in American English as they played basketball or music. Often words used by black kids in the big cities become popular with other kids many years later. Another popular sport, baseball, has also given many words and expressions to American English. On the beaches of southern California, teenagers invented words to describe how they felt when they surfed. These words found their way into the high schools and then to other places. Similar changes in English happened among young people in Ireland and Australia. Children from one group would find ways to play with children of another group more easily. Often they made new words just to develop an identity different from their parents.
