What would you call a world language in Italian?
Google definition: "a language known or spoken in many countries."
World languages are English, Spanish, French.
*There seems to be a second definition: "an artificial language for international use." But that is not what I mean.
I think that the one that I do NOT mean is this: lingua universale, lingua internazionale.
But I am looking for translation of the first meaning ("a language known or spoken in many countries.").
