Let's start with the most useful word in any language. It's simple, friendly, and works in almost any situation.

You can use Olá anytime, day or night, whether you're talking to a friend or a shopkeeper. It's the perfect all-purpose greeting.

Like in English, Brazilians also greet each other based on the time of day. Using the right phrase shows you're paying attention and is a nice touch.

You'll use this from when you wake up until lunchtime.

This is your go-to greeting from noon until the sun starts to set.

Once it gets dark, switch to Boa noite. What's interesting is that it means both "good evening" and "good night." You can use it when you arrive somewhere in the evening and also when you're leaving to go to bed.

Knowing how to be polite can make your interactions much smoother. These next few words are key.

Simple and essential. Use it whenever you're asking for something.

This one is important. In Portuguese, the word for "thank you" changes based on who is speaking.

If you identify as male, you say obrigado. If you identify as female, you say obrigada.

It’s a small detail that shows you've really done your homework.

So, what do you say when someone thanks you?

This is the standard, friendly response. It literally means "of nothing," similar to saying "it was nothing" in English.
