Meanwhile, many africans speak 2 languages in their family, a third one for people that don't speak one of theses two and have studied french and english.
So, exactly how it works in Southeast Asia, especially Indonesian.
They speak native local language from their city, other two from other islands, English for international language, sometimes Chinese, Malay, Arabic, Korean, or Japanese. Not to forget the national language, Indonesian.
Basically most European are the second worste in the world when it comes to language. The worst being the Anglo-Saxon with special mention for the amercain among they who think it is normal to only speak one.
Learning 3+ languages sounds like a lot of work. Colonizing the entire world so that you never have to learn a second language seems like the smarter move if you ask me 🧐
