The Americas, also known as America,[1] are lands of the Western Hemisphere, composed of numerous entities and regions variably defined by geography, politics, and culture.
South America—the continent and associated islands of the Western Hemisphere. It is chiefly in the Southern Hemisphere and lies between the Atlantic and Pacific Oceans, southeast of North America.
British West Indies—the islands and territories of the Caribbean under British colonial influence.
Federal Republic of Central America—formerly the United Provinces of Central America, a federal republic in Central America from 1823 to 1840 comprising the newly independent Spanish territories: Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and (later) Los Altos. In 1838, the federation succumbed to civil war and dissolved.
Anglo-America—the region of the Americas having significant historical, linguistic, and cultural links to England or the British Isles, i.e., Anglophone; often just Canada and the United States.
Latin America—the region of the Americas where Romance languages derived from Latin–namely Spanish, Portuguese, and variably French–are officially or primarily spoken. Though French is spoken in Quebec, it is typically not included due to Canada's links to Britain.
Mesoamerica—a region of the Americas extending from central Mexico southeast to Nicaragua and Costa Rica; a term used especially in archaeology and ethnohistory for the region where an array of civilizations had flourished during the pre-Columbian era, and which shared a number of historical and cultural traditions.
Mesoamerican Linguistic Area—a sprachbund, or linguistic region, defined as the area inhabited by speakers of a set of indigenous languages which have developed certain similarities as a result of their historic and geographical connections; roughly co-terminate with the archaeological/ethnohistorical Mesoamerica.
Aridoamerica—an archaeological/ethnohistorical regional division, essentially comprising the arid/semi-arid northern portion of present-day Mexico, whose historical peoples are generally characterized by a nomadic existence and minimal reliance on agriculture.
Oasisamerica—an occasionally used archaeological/ethnohistorical term for a (pre-Columbian) cultural region of North America.

Since the 16c, a name of the western hemisphere, often in the plural Americas and more or less synonymous with the New World. Since the 18c, a name of the United States of America.
