Standard English and non standard English?

Standard English is the English that is taught in schools. It includes both grammar and phonetics, as well as other areas of language. For example, in Standard English double negatives (I don't want no) are considered ungrammatical while they may be grammatical in other dialects. There are also accepted pronunciations for certain Words, though this is more likely to vary regionally then other aspects of Standard English. In this case, Standard phonetic English can refer to the sort of accent and pronunciations that you hear on the national news.
