Spoken English shows great variation across regions where it is the predominant language. The United Kingdom has a wide variety of accents, and no single "British accent" exists. This article provides an overview of the numerous identifiable variations in pronunciation of English, which shows various regional accents and the UK and Ireland. Such distinctions usually derive from the phonetic inventory of local dialects, as well as from broader differences in the Standard English of different primary-speaking populations.
Accent is the part of dialect concerning local pronunciation. Vocabulary and grammar are described elsewhere; see the list of dialects of the English language. Secondary English speakers tend to carry over the intonation and phonetics of their mother tongue in English speech. For more details on this, see non-native pronunciations of English.
