Dialect is a form of language. It is a way people in an area speak, pronounce, or write some words from the same language differently. In a dialect, the grammar is also different.
For example, in southern parts of the U.S., some words or phrases have different uses, pronunciation, and grammatical structure than the northern U.S. However, both dialects are a part of the English language. Dialects show that language is a changing thing, and there is more than one correct way to say something.
Following are some examples of dialect that show English sounds different in different parts of the U.S.
