This is a list of varieties of the English language. Dialects are varieties differing in pronunciation, vocabulary and grammar from each other and from Standard English (which is itself a dialect). British linguists distinguish dialect from accent, which refers only to pronunciation. Thus, any educated English speaker can use the vocabulary and grammar of Standard English (or Received Pronunciation as it is sometimes known in Britain), but different speakers are said to speak it using their own regional accent. American linguists, however, include pronunciation differences as part of the definition of regional or social dialects (better called varieties).
