terms 'The Queen's English' or 'The King's English' have also been used by some writers, though the terms are more appropriately used to cover grammar as well as pronunciation. The phonetician Jack Windsor Lewis frequently criticised the name "Received Pronunciation" in his blog: he has called it "invidious", a "ridiculously archaic, parochial and question-begging term" and noted that American scholars find the term "quite curious". He used the term "General British" (to parallel "General American") in his 1970s publication of A Concise Pronouncing Dictionary of American and British English and in subsequent publications. The name "General British" is adopted in the latest revision of Gimson's Pronunciation of English. Beverley Collins and Inger Mees use the term "Non-Regional Pronunciation" for what is often otherwise called RP, and reserve the term "Received Pronunciation" for the "upper-class speech of the twentieth century". Received Pronunciation has sometimes been called "Oxford English", as it used to be the accent of most members of the University of Oxford. The Handbook of the International Phonetic Association uses the name "Standard Southern British". Page 4 reads: In her book Kipling's English History (1974) Marghanita Laski refers to this accent as "gentry". "What the Producer and I tried to do was to have each poem spoken in the dialect that was, so far as we could tell, ringing in Kipling's ears when he wrote it. Sometimes the dialect is most appropriately, Gentry. More often, it isn't." Sub-varieties Faced with the difficulty of defining a single standard of RP, some researchers have tried to distinguish between sub-varieties: proposed Conservative, General, and Advanced; "Conservative RP" referred to a traditional accent associated with older speakers with certain social backgrounds; General RP was considered neutral regarding age, occupation or lifestyle of the speaker; and Advanced RP referred to speech of a younger generation of speakers. Later editions (e.g., Gimson 2008) use the terms General, Refined and Regional RP. In the latest revision of Gimson's book, the terms preferred are General British (GB), Conspicuous GB and Regional GB. refers to "mainstream RP" and "U-RP"; he suggests that Gimson's categories of Conservative and Advanced RP referred to the U-RP of the old and young respectively. However, Wells stated, "It is difficult to separate stereotype from reality" with U-RP. Writing on his blog in February 2013, Wells wrote, "If only a very small percentage of English people speak RP, as Trudgill et al. claim, then the
