English language in southern England
South East England and the Home Counties (the counties bordering London) tend to reflect the interface between the London region and other regional accents. Affluent districts are associated with a modified Received Pronunciation (RP) accent, reflecting their traditional popularity with upper middle and upper-class residents which has spread throughout more social classes broadly in rural areas with commuting access to London. Less affluent areas have traditionally mainstream London accents (that is, variants of the Estuary English accent) that grade into southern rural outside urban areas.
Accent (sociolinguistics)
When a group defines a standard pronunciation, speakers who deviate from it are often said to "speak with an accent". However, everyone speaks with an accent. People from the United States would "speak with an accent" from the point of view of an Australian, and vice versa. Accents such as BBC English or General American may sometimes be erroneously designated in their countries of origin as "accentless" to indicate that they offer no obvious clue to the speaker's regional or social background.
