Received Pronunciation, or RP for short, is the instantly recognisable accent often described as ‘typically British’. Popular terms for this accent, such as ‘The Queen’s English’, ‘Oxford English’ or ‘BBC English’ are all a little misleading. The Queen, for instance, speaks an almost unique form of English, while the English we hear at Oxford University or on the BBC is no longer restricted to one type of accent.
RP is an accent, not a dialect, since all RP speakers speak Standard English. In other words, they avoid non-standard grammatical constructions and localised vocabulary characteristic of regional dialects. RP is also regionally non-specific, that is it does not contain any clues about a speaker’s geographic background. But it does reveal a great deal about their social and/or educational background.
