Answer 2

It is not an idiomatic expression - it is the name of a country. The United States of America is often called just America, in the same way that the United States of Mexico is called just Mexico.

America is the name given to the super-continent east of the Pacific Ocean and west of the Atlantic Ocean in honor of explorer Amerigo Vespucci. The name America is often used to refer to the United States of America, and American is the most common word referring to the people of the United States of America, but many, especially in South America, refer to us as North Americans (Norte Americanos), pointing out that we do not have a monopoly on the name America. -HW
