The origin of American English

The origin of American English can be traced back to the colonial period in the late17th century. A group of immigrants from Britain and Ireland began to settle in North America, bringing their own languages and dialects. During their migration, they came into contact with local Indian tribes and Africans in the slave trade, which further influenced the evolution of American English. During the development of American English, it was influenced by British English and other European languages. In particular, London accent and British local dialect have made great contributions to the formation and development of American English.
