The national language of Argentina is Spanish. Argentine Spanish has diverged in many ways from Castilian, showing the effects of the vast influx of foreigners into Buenos Aires, as well as of Spaniards from Andalucía, Galicia, and the Basque provinces. First- and second-generation Italians have added their touch to the language, and French settlers have contributed many Gallicisms.
The outstanding phonetic feature of Argentine Spanish is the yeísmo, in which the ll and y are pronounced like the z in azure. The meaning of many Castilian words also has been modified. The Porteños, as the inhabitants of Buenos Aires are called, rely heavily upon a variety of intonations to express shades of meaning.
English has become increasingly popular as a second language, especially in metropolitan areas and in the business and professional community. There are pockets of Italian and German immigrants speaking their native languages. Some Amerindian languages are still spoken, including a version of Tehuelche in the pampas and Patagonia, Guaraní in Misiones Province, and Quechua in some parts of the Jujuy and Salta provinces.
