The Brummie dialect, or more formally the Birmingham dialect, is spoken by many people in Birmingham, England, and some of its surrounding area. "Brummie" is also a demonym for people from Birmingham. It is often erroneously used in referring to all accents of the West Midlands, as it is markedly distinct from the traditional accent of the adjacent Black Country, but modern-day population mobility has tended to blur the distinction. Population mobility has meant that to a degree, the Brummie accent extends into some parts of the Metropolitan Borough of Solihull, but much of the accent within the borough might be considered to be closer to contemporary Received Pronunciation (RP).
