English has developed 1400 years. The earliest form of English is a group of West Germanic dialects brought to Britain by Anglo-Saxon immigrants in the 5th century A.D., collectively known as Old English. Middle English began at the end of 1 1, and Norman conquered England. This is the period when the language was influenced by French. Early modern English was introduced to the printing press in London in the late15th century, when the King James Bible was printed, and the vowel movement began.

English phonology

English phonology refers to the study of English phonology (that is, phonetic system). Just like all languages, regardless of history, the pronunciation of spoken English varies from dialect to dialect.

This variation is particularly obvious in English, because it is widely used in English-speaking countries in Australia, Canada, the United States, New Zealand, Britain and the Caribbean, and is used as a mother tongue or a second language in every country in the world.

There is no decisive and internationally recognized standard for English, so English in different countries may sometimes hinder communication. Even so, English accents in different regions can be understood.
