American and British English differences

This is one of a series of articles about the differences between American English and British English, which, for the purposes of these articles, are defined as follows:American English (AmE) is the form of English used in the United States.British English (BrE) is the form of English used in the United Kingdom. It includes all English dialects used within the United Kingdom. Written forms of American English are fairly well standardized across the United States. An unofficial standard for spoken American English has developed as a result of mass media and of geographic and social mobility. This standard is generally called a General American or Standard Midwestern accent and dialect, and it can typically be heard from network newscasters, although local newscasters tend toward more provincial forms of speech. Despite this unofficial standard, regional variations of American English have not only persisted, but have actually intensified, according to William Labov.
