PASSAGE
Standard English refers to the authoritative and correct usage of the language, the medium of expression for government and education. Its opposite is a dialectical variant of the language, that is, accepted and recognized words, expressions and structures peculiar to a smaller group of geographical region. For example, Nigerian, American, Irish and British English differ from one another in many respects and each is identifiable, yet in every case the standard variety approaches a single and hypothetical classification known as international English. As one moves towards informality and away from the observance of strict rules, emphasis falls on the differences between dialects. In addition to American English being distinguishable from British English, it is also true that British English is not uniform within the United Kingdom.
