Brazilian Portuguese Greetings
How do you say hello in Brazilian Portuguese?
The most common way to say hello in Brazilian Portuguese is "oi" (pronounced "oy"). It's informal, friendly, and used all day long. For a more formal situation, you'd say "olá" (oh-LAH), and among friends, "e aí" (ee-ah-EE) is the casual go-to. Let's break down exactly when to use each.

Oi: The Everyday Hello
"Oi" is your default greeting in Brazil. It works in almost any casual situation: with friends, coworkers, neighbors, or in a shop. It's warm and simple, and Brazilians say it with a smile, often followed by "tudo bem?" (how's it going?).
Unlike European Portuguese, where "olá" is more common, Brazilians lean heavily on "oi." If you say "olá" in Brazil, it won't be wrong, but it will sound a bit stiff, like saying "good day" in English instead of "hi." Stick with "oi" for daily interactions.
- Use "oi" with anyone your own age or younger, and in most informal settings.
- Pair it with "tudo bem?" to sound natural: "Oi, tudo bem?"
Olá: The Formal Hello
"Olá" (oh-LAH) is the formal or polite version of hello. You'll hear it in business meetings, when addressing older people, or in official settings. It's not cold, just more respectful.
In Brazil, "olá" is less common than "oi" in everyday speech. If you use it with friends, it might sound like you're being distant or joking. Save it for situations where you want to show respect, like talking to a boss or a stranger in a formal context.
- Use "olá" in job interviews, with authority figures, or when you don't know the person well.
- It's perfectly correct, but Brazilians will notice you're being extra polite.
E aí: The Casual "What's Up"
"E aí" (ee-ah-EE) literally means "and there?" but it's used like "what's up?" or "hey." It's very informal and common among friends, especially younger people. You can say just "e aí" as a greeting, or "e aí, tudo bem?" to ask how someone is.
This greeting is distinctly Brazilian. In Portugal, you'd rarely hear it. If you're learning Brazilian Portuguese, using "e aí" will make you sound like a local, but only in casual settings. Avoid it in formal situations or with people you don't know.
- "E aí" is perfect for texting friends or meeting someone at a party.
- Don't use it with your boss or in a professional email.
Time of Day: Bom dia, Boa tarde, Boa noite
Brazilians also greet based on the time of day. "Bom dia" (good morning) is used until noon, "boa tarde" (good afternoon) from noon until evening, and "boa noite" (good night) after dark. These are polite and work in both formal and informal situations.
You can combine them with "oi" for extra friendliness: "Oi, bom dia!" or "Boa tarde, tudo bem?" This is very natural. Note that "boa noite" is used both as a greeting and as a farewell, just like in English.
| Greeting | When to Use | Example |
|---|---|---|
| Oi | Any time, informal | Oi, tudo bem? |
| Olá | Formal, any time | Olá, prazer em conhecê-lo. |
| E aí | Casual, among friends | E aí, cara! Como vai? |
| Bom dia | Morning until noon | Bom dia, tudo bem? |
| Boa tarde | Noon until evening | Boa tarde, como você está? |
| Boa noite | After dark | Boa noite, até amanhã! |
Pronunciation Tips for English Speakers
Pronunciation is key to sounding natural. "Oi" is pronounced like the English "oy" in "boy," but shorter. "Olá" has the stress on the second syllable: oh-LAH. "E aí" is pronounced "ee-ah-EE," with a rising tone on the last syllable.
In Brazil, the "r" in "tudo bem" is often pronounced like an English "h" in some regions, so it might sound like "too-doo beng" with a nasal "e." Don't worry too much about regional accents at first; just focus on the rhythm and intonation.
- Practice saying "oi" with a smile—it changes the sound.
- Listen to Brazilian music or podcasts to hear these greetings in context.
Common Mistakes and How to Avoid Them
One common mistake is using "olá" too often, which can sound overly formal. Another is using "e aí" in a job interview, which would be inappropriate. Also, don't confuse "oi" with the English "oy," which is a complaint in English.
Remember that in Brazilian Portuguese, "você" is used for informal "you," while "tu" is used in some regions. For greetings, it doesn't matter much, but using "você" with "oi" is safe everywhere. If you're learning European Portuguese, note that "tu" is more common, but that's a different variant.
- Don't say "olá" to friends—it sounds distant.
- Avoid "e aí" in formal settings.
- Use "oi" as your default—it's never wrong in casual Brazil.
