Scouse (/ˈskaʊs/; also, in academic sources, called Liverpool English or Merseyside English) is an accent and dialect of English found primarily in the Metropolitan county of Merseyside, and closely associated with the city of Liverpool. The accent extends as far as Flintshire in Wales, Runcorn in Cheshire and Skelmersdale in Lancashire.
The Scouse accent is highly distinctive, and has little in common with those used in the neighbouring regions of Cheshire and Lancashire. The accent itself is not specific to all of Merseyside, with the accents of residents of St Helens and Southport, for example, more commonly associated with the historic Lancastrian accent.
The accent was primarily confined to Liverpool until the 1950s when slum clearance in the city resulted in migration of the populace into new pre-war and post-war developments in surrounding areas of Merseyside. The continued development of the city and its urban areas has brought the accent into contact with areas not historically associated with Liverpool such as Prescot, Whiston and Rainhill in Merseyside and Widnes, Runcorn and Ellesmere Port in Cheshire.
Variations within the accent and dialect are noted, along with popular colloquialisms, that show a growing deviation from the historical Lancashire dialect and a growth in the influence of the accent in the wider area.
