Standard English (often shortened to SE within linguistic circles) refers to whatever form of the English language is accepted as a national norm in any English-speaking country. It encompasses grammar, vocabulary and spelling. In the British Isles, particularly in England and Wales, it is often associated with: the "Received Pronunciation" accent (there are several variants of the accent) and UKSE (United Kingdom Standard English), which refers to grammar and vocabulary. In Scotland the standard is Scottish Standard English. In the United States it is generally associated with (though controversially) the General American accent and in Australia with General Australian. Unlike the case of other standard languages, however, no official or central regulating body defines Standard English.
