American English, or United States (U.S.) English, is the set of dialects 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, considered the de facto language of the country because of its widespread use. English has been given official status by 30 of the 50 state governments. As an example, while both Spanish and English have equivalent status in the local courts of the Commonwealth of Puerto Rico, under federal law, English is the official language for any matters being referred to the United States District Court for the territory.
