American versus British English

United States English or U.S. English, is the set of varieties of the English language native to the United States.
English is the most widely spoken language in the United States and is the common language used by the federal government.

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 been influenced by the languages of West Africa, the Native American population, German, Dutch, Irish, Spanish, and other languages of successive waves of immigrants to the United States.
