American English
American English, sometimes called 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 U.S., as well as the common language used in government, education, and commerce in all 50 states, the District of Columbia, and in all U.S. territories except Puerto Rico. Since the late 20th century, American English has become the most influential form of English worldwide.
Varieties of American English include many patterns of pronunciation, vocabulary, grammar, and particularly spelling that are unified nationwide but distinct from other forms of English around the world. Any American or Canadian accent perceived as lacking noticeably local, ethnic, or cultural markers is known in linguistics as General American; it covers a fairly uniform accent continuum native to certain regions of the U.S. especially associated with broadcast mass media and highly educated speech.
