El Salvador (República de El Salvador, Spanish pronunciation: [re̞ˈpuβ̞lika ð̞e̞ (e̞)l salβ̞aˈð̞o̞ɾ]) is a country in Central America. The area was originally called by the Pipil "Cuzhcatl", in Spanish "Cuzcatlan", which in Nahuatl means "the land of precious things." After the Spanish conquest, the land was baptized by Spanish conquistadors as "Provincia De Nuestro Señor Jesucristo El Salvador Del Mundo" ("Province of Our Lord Jesus Christ, The Savior Of The World"), now abbreviated as "República de El Salvador". The country borders the Pacific Ocean between Guatemala and Honduras. With a population of approximately 5.8 million people, it is the most densely populated nation in Central America and is undergoing rapid industrialization. El Salvador is located in Central America. It has a total area of 8,123 square miles (21,040 km²), smaller than that of the U.S. state of Massachusetts. It is the smallest country in continental America, and is affectionately called the "Tom Thumb of the Americas" ("Pulgarcito de America"). It has 123.6 square miles (320& km²) of water within its borders. Several small rivers flow through El Salvador into the Pacific Ocean, including the Goascorán, Jiboa, Torola, Paz and the Río Grande de San Miguel. Only the largest river, the Lempa River, flowing from Honduras across El Salvador to the ocean, is navigable for commercial traffic. Volcanic craters enclose lakes, the most important of which are Lake Ilopango (70 km²/27 sq mi) and Lake Coatepeque (26 km²/10 sq mi). Lake Güija is El Salvador's largest natural lake (44 km²/17 sq mi). Several artificial lakes were created by the damming of the Lempa, the largest of which is Embalse Cerrón Grande (350 km²/135 sq mi). El Salvador shares borders with Guatemala (126 mi/203 km) and Honduras (212.5 mi/342 km). It is the only Central American country that does not have a Caribbean coastline. The highest point in the country is Cerro El Pital at 8,957 feet (2,730 meters), which shares a border with Honduras.
