Here's what you should expect:
* Tourists areas: You'll likely find people who speak some English in tourist areas, especially hotels, restaurants, and shops catering to international visitors.
* Local areas: English is less common in everyday life and outside of tourist areas. You'll probably find it difficult to get by without at least some basic Portuguese.
* Younger generation: Younger generations are more likely to have some English proficiency due to exposure to English media and the internet.
It's always a good idea to learn a few basic Portuguese phrases before your trip to Rio. This will help you navigate the city more easily and make your experience more enjoyable.
Don't be afraid to use your basic Portuguese; even a little effort will go a long way!
