American English has many dialects , especially the midwestern,southern,African American and Spanish dialects .Even in some parts of the USA, two people from neighbouring towns speak a little differently.American English has so many dialects because people have come from all over the world.Geography also plays a part in making dialects. Some people who live in the mountains lf the eastern USA speak with an older kind of English dialect.When Americans moved from one place to another,they took their dialects with them.So people from the mountains in the southeastern USA speak with almost the same dialect as people in the northwestern USA.The USA is a large country in which many different dialects are spoken. Although many Americans move a lot,they still recognize and understand each other’s dialects
