Etymology and Naming of“America”- USA history

Amerigo Vespucci(Italian, explorer) who got to know Christopher Columbus's U.S. ocean space attainment explored the South America northern coast, and announced the letter of the falsehood of "I reached earlier at it one year ago than Columbus." in 1503.

In response, Waldseemuller (a German and a cartographer) who was sure that this land is not India but the new continent which Columbus says, Writing "a guide to a space magazine" (Cosmographiae Introductio) of Latin published in France in 1507 In expository writing, This new continent from the name of Amerigo Vespucci who is "discovery" person Amerige, From or Latin name Americus Vespucius, It was advocated that it should have been called the United States (America) which is the same female form as Europe, Africa, and Asia.
In addition, in Spain and its colony, a name called the United States was not used but the new continent was known as Las Indias.

Although, as for Waldseemuller, Vespucci got to know that he was not a first "discovery" person of new land later, the name of the United States was already fixed to all Europe.

Etymology and Naming

The earliest known use of the name America dates to April 25, 1507, where it was applied to what is now known as South America. It appears on a small globe map with twelve time zones, together with the largest wall map made to date, both created by the German cartographer Martin Waldseemuller in Saint-Die-des-Vosges in France. These were the first maps to show the Americas as a land mass separate from Asia. An accompanying book, Cosmographiae Introductio, anonymous but apparently written by Waldseemuller's collaborator Matthias Ringmann, states, "I do not see what right any one would have to object to calling this part [that is, the South American mainland], after Americus who discovered it and who is a man of intelligence, Amerigen, that is, the Land of Americus, or America: since both Europa and Asia got their names from women". Americus Vespucius is the Latinized version of the Florentine explorer Amerigo Vespucci's name, and America is the feminine form of Americus. Amerigen is e
xplained as Amerigo plus gen, the accusative case of the Greek word for 'earth', and meaning 'land of Amerigo'. (See etymology.) Amerigo itself is an Italian form of the medieval Latin Emericus (see also Saint Emeric of Hungary), which through the German form Heinrich (in English, Henry) derived from the Germanic name Haimirich.
Vespucci was apparently unaware of the use of his name to refer to the new landmass, as Waldseemuller's maps did not reach Spain until a few years after his death. Ringmann may have been misled into crediting Vespucci by the widely published Soderini Letter, a sensationalized version of one of Vespucci's actual letters reporting on the mapping of the South American coast, which glamorized his discoveries and implied that he had recognized that South America was a continent separate from Asia; in fact, it is not known what Vespucci believed on this count, and he may have died believing what Columbus had, that they had reached the East Indies in Asia rather than a new continent.
Spain officially refused to accept the name America for two centuries, saying that Columbus should get credit, and Waldseemuller's later maps, after Ringmann's death, did not include it; however, usage was established when Gerardus Mercator applied the name to the entire New World in his 1538 world map. Acceptance may have been aided by the "natural poetic counterpart" that the name America made with Asia, Africa, and Europa.
In modern English, North and South America are generally considered separate continents, and taken together are called the Americas in the plural, parallel to similar situations such as the Carolinas. When conceived as a unitary continent, the form is generally the continent of America in the singular. However, without a clarifying context, singular America commonly refers in English to the United States of America.
