In Brazil, do they speak Spanish ?
Welcome to SpanishDict. Some folks here are learning Spanish, and others English, so please post your questions with proper grammar, spelling and punctuation.
This is the kind of research that is very easy to do for yourself. I'll give you a clue: people in Brazil speak Spanish if they have learned to speak Spanish.
Here is another clue: the capital of Brazil is Rio de Janeiro (river of January). And January in Spanish is "enero".
in Brasil (with S ) people speak portuguese because it was colonised by Portugal. And another fact is that the capital of a Brasil in not Rio de Janeiro it is Brasilia

From what I understand, Brazil (Brasil in Portuguese and Spanish) has a huge demand for Spanish teachers, so I guess it must be either very popular, or desirable.
However, I haven't had problems either understanding or getting understood by Brazilian people, provided that we all keep the speed, the pronunciation and the slang under control.
I have a couple of friends living in Brazil and they speak Spanish. They also speak English and they are learning Portughese.
