How to say this in Spanish?

¿Qué idiomas hablan en Chile? (Plural, it's a general question)

¿Qué idiomas hablas en Chile? (Singular, this would only apply to the person you are asking and it sounds a bit odd actually)

The first option is more correct. You can either say Idiomas or Lenguas, but i prefer Idiomas.

SInce you are using the pronoun "you" in Spanish, it could be three different ways depending on the context and on what you are trying to say:

"Qué idiomas hablas en Chile?" (You singular, informal)

"Qué idiomas habla en Chile?" (You singular, formal)

"Qué idiomas hablan en Chile?" (You plural)

¿Cuáles idiomas se habla en Chile?

Using the se makes it impersonal. So in English we always say "you" or "they" but we don't mean specific people. What I wrote says something like "what languages are spoken in Chile?"

?Cuáles son los idiomas que se hablan en Chile?

The introductory question mark should be inverted but my PC is not up to printing that.
