The Different languages of South America

I just came across a very interesting study about the different languages that are spoken in South America. My first reaction was to think of Spanish, then Portuguese, and then some smaller indigenous languages.

But the results were more interesting.

Portuguese is the most spoken language in South America. It is the official language of Brazil, which holds about 51% of the South American population. Spanish is the official language of most countries of the continent. Dutch is the official language of Suriname; English is the official language of Guyana , although there are at least twelve other languages spoken in the country such as Hindi, Arabic, Portuguese and various indigenous dialects. English is also spoken in the Falkland Islands. French is the official language of French Guiana.
