This is an introduction to the phonology of present-day English. It deals principally with three varieties of English: "General American," Southern British "Received Pronunciation" and "Scottish Standard English." It offers a systematic and detailed discussion of the features shared by these major accents, and explains some major differences. Other varieties of English--Australian and New Zealand English, South African English and Hiberno-English--are also discussed briefly. Without focusing on current phonological theory and its evolution, the author demonstrates the importance of "theory," in whatever shape or form, in phonological argumentation. This textbook will be welcomed by all students of English language and linguistics.
