Buenos Aires: What's in a name?

And where are you going to on vacation? "I'm going to: Ciudad de la Santísima Trinidad y Puerto de Santa María del Buen Aire." Que, Como, Dondé?????

"Buenos Aires was originally called Ciudad de la Santísima Trinidad y Puerto de Santa María del Buen Aire, "City of the Most Holy Trinity and Port of Saint Mary of the Fair Winds"

The city name was chosen by the chaplain of Mendoza's expedition, who was a devout follower of the Virgine de Bonaria ("Our Lady of the Fair Winds") of Cagliari, Sardinia.

Argentines sometimes refer to the city as Capital Federal to differentiate the city from the province of the same name. In the 1994 constitution, the city was given autonomy, hence its formal name: Ciudad Autónoma de Buenos Aires.

The abbreviations Bs. As. and Baires are sometimes used, the first one mostly in writing and the second one in everyday speech. The city is sometimes called La reina del Plata ("The Queen of the Plata")."
