Aspect of American English: I believe most of us must have this experience that when we look up a word in a dictionary we will find the word "BrE" or "AmE" marked behind "BrE" here means British English (here called BrE) while AmE means American English (here called AmE). So I can say that AmE has become more and more popular in all English-speaking countries, especially among young people. To some extent it has become more common than BrE. So how did it come about? I think there are various reasons. To get a general idea, let's go back to the American past. I think the formation of 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 a great contribution to Europe. Just as a coin has two sides, it will be the beginning of a great disaster for the people living in the New Continent. The English began establishing permanent settlements in North America in the early 17th century. Because in that period English-language capitalism had experienced strong 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 English established 13 colonies along the east coast of North America. They 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. The opportunities and pursuit of religious persecution attracted many Englishmen to America. By 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 in the 13 colonies developed very rapidly. As the economy developed, the inhabitants of the colonies wanted more freedom in every aspect of social life.
