The regional accents of English speakers show great variation across the areas where English is spoken as a first language. This article provides an overview of the many identifiable variations in pronunciation, usually deriving from the phoneme inventory of the local dialect, of the local variety of Standard English between various populations of native English speakers. Local accents are part of local dialects. Any dialect of English has unique features in pronunciation, vocabulary, and grammar. The term "accent" describes only the first of these, namely, pronunciation. See also: List of dialects of the English language.
