Buenos Aires (/ bwens riz / or /-ars /; Spanish pronunciation: (bwenos aies)) is the capital and most populous city of Argentina. The city is located on the western shore of the estuary of the Rio de la Plata, on the South American continent's southeastern coast. 'Buenos Aires' can be translated as 'fair winds' or 'good airs', but the former was the meaning intended by the founders in the 16th century, by the use of the original name 'Real de Nuestra Senora Santa Maria del Buen Ayre'. The Greater Buenos Aires conurbation, which also includes several Buenos Aires Province districts, constitutes the fourth-most populous metropolitan area in the Americas, with a population of around 17 million.
