The variety of a language which has the highest status in a community or nation and which is usually based on the speech and writing of educated native speakers of the language. A standard variety is generally
- used in the news media and literature.
- described in dictionaries and grammars.
- taught in schools and taught to non-native speakers when they learn the language as a foreign language.
Sometimes it is the educated variety spoken in the political or cultural center of a country. (...) The standard variety of American English is known as Standard American English. These national standard varieties have differences in spelling, vocabulary, grammar, and particularly pronunciation, but there is a common language. This makes it possible for educated native speakers of the various national standard varieties of English to communicate with one another (Longman Dictionary of Language Teaching and Applied Linguistics, p.351)
