The historical origin of English:

The earliest form of English is called Old English or Anglo-Saxon (AD 550- 1066). Old English developed from a group of Germanic dialects in the North Sea, which were originally used by Germanic tribes (called Angles, Saxons and Jutes) in frys, Lower Saxony, Jutland and the southern coastal areas of Sweden.

From the settlement of Anglo-Saxons in England in the 5th century A.D. to the economic and administrative collapse of Rome. In the 7th century, the Germanic language of Anglo-Saxons ruled Britain, replacing the language of Roman Britain (43-409 CE): ancient Britten, a Celtic language and Latin, was brought to England and occupied by the Romans.

With the development of modern English, official media such as public education and state-funded publications have published and disseminated clear norms of standard usage. 1755, samuel johnson published the English Dictionary, which introduced the standard spelling and usage of words.

1828, noah webster published American English Dictionary, trying to establish American English speaking and writing norms independent of British standards. In Britain, the characteristics of nonstandard or inferior dialects are increasingly discriminated against, which leads to the rapid spread of prestigious variants among the middle class.
