English language in England
There are many different accents and dialects throughout England and people are often very proud of their local accent or dialect. However, accents and dialects also highlight social class differences, rivalries or other associated prejudices—as illustrated by George Bernard Shaw's comment:
Cardiff English
Although based in nearby Barry, accents heard in the sitcom "Gavin & Stacey" are not Cardiff or Barry accents, with the exception of the character Nessa, played by Ruth Jones who was brought up in Bridgend but now resides in Cardiff.
