Quick Scoop: What do they speak in Argentina?

• The primary language used in daily life, media, schools, and government is Spanish.
• The local variety has a distinct accent and slang (often called Rioplatense Spanish), especially around Buenos Aires.
• People frequently use “vos” instead of “tú” for “you,” which changes some verb forms (this is known as voseo).
• In some regions, there are also indigenous languages (like Guaraní in the northeast) and communities that speak Italian, German, Welsh, and others, but these are much smaller in number compared to Spanish.

Tiny example

If standard Spanish says “¿Tú puedes venir?” (“Can you come?”), in Argentina you’ll often hear “¿Vos podés venir?”—same meaning, just the local style. TL;DR: If you go to Argentina, Spanish will get you around almost everywhere; just be ready for a unique accent and the use of “vos.”
