American English is a set of dialects of the English language used mostly in the United States. Approximately two-thirds of the world’s native speakers of English live in the United States.
English is the most common language in the United States. Though the U.S. federal government has no official language, English is the common language used by the federal government and is considered the de facto language of the United States because of its widespread use. English has been given official status by 28 of the 50 state governments. The use of English in the United States was a result of English colonization. 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, and immigration.
