what factor about america has contributed to the evolution of american english
American English The use of English in the United States is a result of British colonization of the Americas. The first wave of English-speaking settlers arrived in North America during the 17th century, followed by further migrations in the 18th and 19th centuries. Since then, American English has developed into new dialects, in some cases under the influence of West African and Native American languages, German, Dutch, Irish, Spanish, and other languages of successive waves of immigrants to the United States.
