How did American spoken English evolve in history and how did it stand out from British spoken English?

American English originated from Elizabethan English, and its history is closely related to the history of American immigration, dating back more than 300 years. 1607, the first colonists, including John Smith, crossed the Atlantic Ocean in three big ships and established Jamestown at the mouth of James River in Virginia. Soon after, 1620, Puritans from Norfolk and Suffolk in the east of England arrived in Plymouth in the southeast of Massachusetts on the ship "Mayflower" and established a colony. At that time, Britain was in the period of Elizabeth I, and it was in the early stage of modern English from the perspective of English development history. Among the first pilgrims who moved to New England, 100 was a graduate of Oxford University and Cambridge University. They brought Elizabethan English to the New World of North America and became the starting point of American English. Since then, both countries have spoken Elizabethan English. Therefore, there is no significant difference between American English and British English for a long time.

As early as the British colonial period, British immigrants in the United States kept close contact with their hometown at first, and their language changed with the change of their mother tongue English, but with the passage of time, an English different from their mother tongue English was also produced in the British colonies in the United States.

From the beginning of17th century when English Puritans set foot on American soil to a long time later, there was no obvious difference between American English and British English. The victory of American War of Independence is a historic turning point, which marks the emergence of a brand-new American English. Revolutionaries tried to get rid of British rule in every field of life. Among them, Benjamin Franklin published an article entitled "America's plan to adopt a new alphabet and reform spelling patterns". Although this plan was not adopted, it had a great influence on lexicographer and lexicographer noah webster. His theory has given some words new spelling methods, such as Honor instead of honor and Theater instead of theater. It can be said that Franklin was a pioneer in the history of English development.

Noah webster is the most famous lexicographer in America. His American English Dictionary was published in 1828, which marked the peak of his contribution to American English. He systematically and comprehensively fixed the composition, meaning and usage of American words, and finally formed a standardized national language in the United States. This laid a solid foundation for the future development of American English and its influence on the world, and Americans have a dictionary of their own pronunciation since then.

Slowly, American English took a different path from British English.
