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:
Phonological history of English consonants
Certain English accents feature variant pronunciations of these sounds. These include fronting, where they merge with /f/ and /v/ (found in Cockney and some other dialects); stopping, where they approach /t/ and /d/ (as in some Irish speech); alveolarization, where they become (in some African varieties); and debuccalization, where becomes before a vowel (found in some Scottish English).
