Received Pronunciation (RP) is the accent traditionally regarded as the standard and most prestigious form of spoken British English. For over a century, there has been argument over such questions as the definition of RP, whether it is geographically neutral, how many speakers there are, whether sub-varieties exist, how appropriate a choice it is as a standard and how the accent has changed over time. The name itself is controversial. RP is an accent, so the study of RP is concerned only with matters of pronunciation; other areas relevant to the study of language standards such as vocabulary, grammar, and style are not considered.
RP has most in common with the dialects of South East Midlands, namely London, Oxford and Cambridge. By the end of the 15th century, "Standard English" was established in the City of London, though it did not begin to resemble RP until the late 19th century.
The introduction of the term Received Pronunciation is usually credited to the British phonetician Daniel Jones. In the first edition of the English Pronouncing Dictionary (1917), he named the accent "Public School Pronunciation"; for the second edition in 1926 he wrote: "In what follows I call it Received Pronunciation, for want of a better term." However, the term had been used much earlier by P. S. Du Ponceau in 1818 and the Oxford English Dictionary cites quotations back to about 1710. A similar term, received standard, was coined by Henry C. K. Wyld in 1927. The early phonetician Alexander John Ellis used both terms interchangeably, but with a much broader definition than Jones's, saying, "There is no such thing as a uniform educated pron. of English, and rp. and rs. is a variable quantity differing from individual to individual, although all its varieties are 'received', understood and mainly unnoticed".
According to Fowler's Modern English Usage (1965), "the correct term is 'the Received Pronunciation'. The word 'received' conveys its original meaning of 'accepted' or 'approved', as in 'received wisdom'.
