Many languages are used, or historically have been used in the United States. The most commonly used language is English. There are also many languages indigenous to North America or to U.S. states or holdings in the Pacific region. Languages brought to the country by colonists or immigrants from Europe, Asia, or other parts of the world make up a large portion of the languages currently used; several languages, including creoles and sign languages, have also developed in the United States. Approximately 337 languages are spoken or signed by the population, of which 176 are indigenous to the area. Fifty-two languages formerly spoken in the country's territory are now extinct.
The Eastern Algonquian languages constitute a subgroup of the Algonquian languages. Prior to European contact, Eastern Algonquian consisted of at least seventeen languages collectively occupying the Atlantic coast of North America and adjacent inland areas, from what are now known as the Canadian Maritime provinces to North Carolina. The available information about individual languages varies widely. Some are known only from one or two documents containing words and phrases collected by missionaries, explorers or settlers, and some documents contain fragmentary evidence about more than one language or dialect. Nearly all of the Eastern Algonquian languages are extinct. Mi'kmaq and Malecite-Passamaquoddy have appreciable numbers of speakers, while Western Abnaki and Delaware are each reported to have fewer than ten speakers post 2000.
Eastern Algonquian constitutes a separate genetic subgroup within Algonquian. Two other groups of Algonquian languages that are recognized, Plains Algonquian, and Central Algonquian; are geographic, and do not refer to genetic subgroupings.
The languages of North America reflect not only that continent's indigenous peoples, but the European colonization as well. The most widely spoken languages in North America (which includes Central America and the Caribbean islands) are English, Spanish, French, Danish (almost entirely exclusive to Greenland alone), and, especially in the Caribbean, creole languages lexified by them.
