Spanish, in a very particular way.

"The official language of Argentina is Spanish, usually called castellano (Castilian) by Argentines. A phonetic study conducted by the Laboratory for Sensory Investigations of CONICET and the University of Toronto showed that the accent of the inhabitants of Buenos Aires (known as porteños) is closer to the Neapolitan dialect of Italian than any other spoken language. Italian immigration and other European immigrations influenced Lunfardo, the slang spoken in the Río de la Plata region, permeating the vernacular vocabulary of other regions as well. Argentines are the largest Spanish-speaking society that universally employs what is known as voseo (the use of the pronoun vos instead of tú (you), which occasions the use of alternate verb forms as well). The most prevalent dialect is Rioplatense, whose speakers are primarily located in the basin of the Río de la Plata. According to one survey, there are around 1.5 million Italian speakers (which makes it the second most spoken language in the country) and 1 million speakers of North Levantine Spoken Arabic. Standard German is spoken by between 400,000 and 500,000 Argentines of German ancestry, though it has also been stated that the there could be as many as 1.8 million. German is the third or fourth most spoken language in Argentina. Some indigenous communities have retained their original languages. Guaraní is spoken by some in the northeast, especially in Corrientes (where it enjoys official status) and Misiones. Quechua is spoken by some in the northwest and has a local variant in Santiago del Estero. Aymara is spoken by members of the Bolivian community who migrated to Argentina from Bolivia. In Patagonia there are several Welsh-speaking communities, with some 25,000 estimated second-language speakers. More recent immigrants have brought Chinese and Korean, mostly to Buenos Aires. English, Brazilian Portuguese and French are also spoken. English is commonly taught at schools as a second language and, to a lesser extent, Portuguese and French."
