Argentina

Argentina, officially the Argentine Republic, is the second largest country in South America by land area, after Brazil. It is constituted as a federation of 23 provinces and an autonomous city, Buenos Aires. It is the eighth-largest country in the world by land area and the largest among Spanish-speaking nations. Argentina's continental area is between the Andes mountain range in the west and the Atlantic Ocean in the east. It borders Paraguay and Bolivia to the north, Brazil and Uruguay to the northeast, and Chile to the west and south. Argentina is Latin America's third-largest economy, with a very high rating on the Human development index. The de facto official language of Argentina is Spanish, usually called castellano (Castilian) by Argentines. Argentina is the largest Spanish-speaking society that universally employs voseo (the use of the pronoun vos instead of tú (you), which occasions the use of alternate verb forms as well.
