Brazilian Portuguese politeness
How do you say yes and no politely in Brazilian Portuguese?
The short answer: yes is usually just sim, but no is rarely a bare não. Brazilians soften refusals with small words like não, obrigado, não consigo, or acho que não, and they often add a reason or an alternative. Saying a flat não can sound abrupt, so the polite version is almost always a short phrase, not a single word.

Yes is simple, but the tone matters
For a plain yes, sim works in any situation. In everyday speech Brazilians often say isso, claro, or com certeza instead of sim, especially when they are agreeing with someone. The word sim is correct and polite, but it can sound formal or stiff in a casual conversation.
If you are accepting an offer, obrigado or obrigada is the natural companion to sim. Men say obrigado, women say obrigada. A simple sim, obrigado is already polite and complete. You do not need to add more.
- Sim, obrigado. Yes, thank you. (said by a man)
- Sim, obrigada. Yes, thank you. (said by a woman)
- Claro, pode deixar. Of course, leave it to me.
- Com certeza. Certainly.
No is rarely just não
A bare não can sound cold or final in Brazilian Portuguese. Even when the answer is clearly no, Brazilians usually add a softener: não, obrigado, acho que não, or não consigo. The softener does not change the answer, it changes the tone.
The most common pattern is não plus a small word of thanks or explanation. Não, obrigado is the standard polite refusal. Não, obrigada is the same from a woman. If you are refusing an invitation, não vou poder ir is softer than não.
| Situation | Polite Brazilian Portuguese | English |
|---|---|---|
| Refusing food or drink | Não, obrigado. / Não, obrigada. | No, thank you. |
| Refusing an invitation | Não vou poder ir, desculpa. | I won't be able to go, sorry. |
| Saying you don't agree | Acho que não. | I think not. |
| Saying you can't | Não consigo, desculpa. | I can't, sorry. |
| Saying you don't want to | Não quero, obrigado. / obrigada. | I don't want any, thank you. |
| Softening a clear no | Infelizmente não. | Unfortunately not. |
The softening words that do the work
Brazilians use a small set of words to take the edge off a no: acho que, infelizmente, desculpa, and obrigado or obrigada. Acho que não is softer than não because it presents the no as an opinion, not a wall. Infelizmente não adds regret without changing the answer.
Another common pattern is to give a reason or an alternative. Não posso agora, mas amanhã posso is a no with a door left open. Não gosto muito is softer than não gosto. These are not tricks, they are the normal rhythm of polite Brazilian speech.
- Acho que não. I think not. (softer than não)
- Infelizmente não. Unfortunately not.
- Não posso agora. I can't right now.
- Não gosto muito. I don't like it much. (softer than não gosto)
- Desculpa, mas não. Sorry, but no.
Yes and no on the phone or in messages
In written messages, Brazilians often use não, obrigado or não, valeu. Valeu is a casual thanks, so não, valeu is a friendly no between people who know each other. In a more formal message, use não, obrigado or não, muito obrigado.
For yes in a message, sim or claro works. A single ok is also common but very casual. If you are replying to a work message, sim, combinado is clear and polite. Combinado means agreed, and it closes the exchange neatly.
What not to say if you want to sound polite
Avoid a bare não with no softener, especially to someone older or in a service situation. Avoid não quero with no obrigado, which can sound blunt. And avoid translating English sorry literally as desculpe in every refusal; desculpa is more common in everyday Brazilian speech.
One more warning: European Portuguese often uses different polite formulas, and some of them sound wrong or unnatural in Brazil. If you learn a phrase from a Portugal-based source, check it with a Brazilian before using it. The grammar is similar, but the politeness habits are not.
How to practise this without sounding translated
The best way to learn these patterns is to hear them in short, real exchanges and repeat them until they feel normal. Start with three phrases: não, obrigado, acho que não, and não vou poder. Use them in low-pressure situations like a café or a shop, where a polite no is expected and easy to recover from.
If you want guided practice, I teach Brazilian Portuguese online to English speakers in the evening. I do not teach European Portuguese and I do not prepare anyone for the CIPLE exam, because that exam tests European Portuguese and marks Brazilian usage wrong.

Common questions
Is it rude to say just não in Brazilian Portuguese?
A bare não is not a swear word, but it can sound abrupt or cold, especially to someone older or in a service situation. Brazilians usually add a softener such as obrigado, acho que não, or desculpa. If you are unsure, use não, obrigado or não, obrigada.
What is the difference between obrigado and obrigada?
Obrigado is said by a man, obrigada by a woman. The word agrees with the speaker, not with the person being thanked. So a woman says não, obrigada even when speaking to a man.
How do I politely refuse an invitation in Brazilian Portuguese?
Use não vou poder ir, desculpa or infelizmente não vou poder. Adding desculpa or infelizmente softens the refusal. You can also offer an alternative, such as não posso hoje, mas amanhã posso.
Is acho que não the same as não?
It means the same thing in practice, but acho que não is softer because it presents the no as an opinion. It is very common when you disagree politely or when you are not completely certain. A bare não is more direct.
Can I use European Portuguese polite phrases in Brazil?
Some will be understood, but many sound unnatural or too formal in Brazil. Politeness habits differ between the two countries, so a phrase that is normal in Portugal can feel stiff in Brazil. Learn the Brazilian patterns if you are going to Brazil or speaking with Brazilians.
Do you teach these phrases in your lessons?
Yes, I teach Brazilian Portuguese online to English speakers in the evening, including polite refusals and everyday conversation. I do not teach European Portuguese or prepare students for the CIPLE exam, because that exam tests European Portuguese and marks Brazilian usage wrong. The paid diagnostic lesson is 45 EUR and is credited against a later package.
