Appearance of American English: I believe that most of us must have this experience that when we look up a word in a dictionary, we find the word "BrE" or "AmE" marked behind the word "BrE" here means British English (here called BrE) while AmE means American English (here called AmE). So I can say that AmE is becoming more and more popular in English-speaking countries, especially among young people. To some extent it has become more common than BrE. So how was he born? I think the reason is different. To get a general idea, let's go back to America's past. I am thinking of the formation of the AmE. can be traced back to the 17th century, when the English began to establish colonial lands. In the late 15th century, Christopher Columbus, an Italian navigator, believed that by sailing west from Europe he could reach the Far East. small islands in 1492, he thought he had reached Asia and did not know that he had discovered a new continent. Columbus made great contributions to Europe. Just like a coin has two sides, this is the beginning of a great disaster for the populations living on the New Continent. The English began establishing permanent colonies in North America in the early 17th century. Because at that time English capitalism had experienced great development and colonial expansion was the first thing to do. Unfortunately, America was his target. The first permanent English settlement was found at Jamestown in 1607 in Virginia. This was organized by the London Company and the Polymouth Company with a charter from the English King James I. Between 1607 and 1733, the British established 13 colonies along the east coast of North America. These were Massachusetts, Rhode Island, New Hampshire, Connecticut, Maine, Vermont, New England, Pennsylvania, New York, New Jersey, Delaware, Virginia, Maryland, North Carolina, South Carolina and Georgia. Opportunity and the pursuit of religious persecution attracted many Englishmen to America. Around 1750, nearly 2 million people lived in these colonies. So they brought many things to America, including language. At the same time, the commonly used language was English, Elizabethan English. The economy of the 13 colonies developed very quickly. With the development of the economy, the inhabitants of the colonies wanted more freedom in all aspects of social life..
