A standard language is a variety of language that is used by governments, in the media, in schools and for international communication. There are different standard varieties of English in the world, such as North American English, Australian English and Indian English. Although these standard varieties differ in terms of their pronunciation, there are few differences in grammar between them. In contrast, there are non-standard forms of a language that are used, for example, in different regional dialects and these non-standard varieties are different from each other.
