* "Speak English in Brazilian" doesn't make grammatical sense. You can't speak a language *in* another language. It's like saying "eat food in a chair."
* What you're probably asking is if Brazilians speak English.
If that's the case, the answer is: It depends!
* Some Brazilians speak English very well. This is especially true in larger cities and tourist areas.
* Many Brazilians speak at least some English. They might understand basic phrases or be able to get by in simple conversations.
* Some Brazilians don't speak English at all. This is more common in smaller towns and rural areas.
Would you like me to answer a different question about English and Brazilian culture?
