Puerto Rico ( /ˌpwɛərtə ˈriːkoʊ/ or /ˌpɔrtə ˈriːkoʊ/), officially the Commonwealth of Puerto Rico (Spanish: “Estado Libre Asociado de Puerto Rico” — literally Associated Free State of Puerto Rico), is an unincorporated territory of the United States, located in the northeastern Caribbean Sea, east of the Dominican Republic and west of the Virgin Islands.
Puerto Rico (Spanish for “rich port”) is composed of an archipelago that includes the main island of Puerto Rico and a number of smaller islands, the largest of which are Vieques, Culebra, and Mona.
The main island of Puerto Rico is the smallest by land area of the Greater Antilles. It, however, ranks third in population among that group of four islands, which also include Cuba, Hispaniola, and Jamaica.
Puerto Ricans often call the island Borinquen, from Borikén, its indigenous Taíno name. The terms boricua and borincano derive from Borikén and Borinquen respectively, and are commonly used to identify someone of Puerto Rican heritage.
The island is also popularly known in Spanish as “La Isla del Encanto” which means “The Island of Enchantment” in English.
