A region of southern North America extending from the southern border of Mexico to the northern border of Colombia. It separates the Caribbean Sea from the Pacific Ocean and is linked to South America by the Isthmus of Panama.
Central America is a region of North America, technically southern North America.
The land between South America and the U.S. (or, in the opinion of some, Mexico). I often consider Caribbean countries to be part of Central America.

Lucas: Isn't that technically part of North America?
Percy: Isn't your mom technically your dad, too?
