The term is a relatively recent and less ambiguous alternative to the term America, which may refer to either the entire landmass or the colloquial name for the United States of America. The original usage to describe what is sometimes considered a single continent or supercontinent is deprecated for clarity, for which the Americas is used to collectively refer to the landmass and various regions of it. When used to describe a single landmass, analogous terms to America or (the) Americas are Eurasia, which consists of Europe and Asia collectively, and Eurafrasia, which is Eurasia and Africa.
Naming of America
The earliest known use of the name America for this particular landmass dates from 1507. It appears on a globe and a large map created by the German cartographer Martin Waldseemüller in Saint-Dié-des-Vosges. An accompanying book, Cosmographiae Introductio, explains that the name was derived from the Latinized version of the explorer Amerigo Vespucci's name, Americus Vespucius, in its feminine form, America, as the other continents all have Latin feminine names.
