How to Say Yes and No in Portuguese (and Sound Natural)
Saying yes and no in Portuguese looks simple until a real conversation starts and people answer without either word. This guide gives you the core words, the polite versions, and the little habits that make you sound natural instead of textbook.

What's in this guide
The two words you need first
Portuguese keeps the basics clean. Start with these:
- Sim (seeng) means yes. The final sound is nasal, so let the m hum in your nose rather than closing your lips hard.
- Nao (nowng) means no. It is also nasal, and it is the same word used for negating verbs, so you will hear it constantly.
These work in Brazil and Portugal, in shops, on the phone, and with strangers. If you learn nothing else today, learn to pronounce the nasal endings, because a flat sim that rhymes with the English word seem is one of the clearest giveaways of a beginner. Say them out loud a few times until the air moves through your nose.
Why Portuguese speakers often skip sim
Here is the part textbooks bury. In everyday speech, Portuguese speakers frequently answer a yes or no question by repeating the verb instead of saying sim.
- Question: Voce fala ingles? (do you speak English?) Answer: Falo (I speak), meaning yes.
- Question: Voce gostou? (did you like it?) Answer: Gostei (I liked it), meaning yes.
To say no this way, you put nao before the verb: Nao falo (I do not speak). Saying a bare sim is not wrong, but echoing the verb sounds warmer and more fluent. Once you notice this pattern, you will hear it everywhere, and copying it is one of the fastest ways to stop sounding like a phrasebook.
Saying yes and no with feeling
When you want to sound sure, Portuguese loves repetition. Doubling the word adds emphasis in a friendly way.
- Sim, sim (seeng seeng) is an enthusiastic yes, like yes, absolutely.
- Nao, nao (nowng nowng) softens a refusal while making it firmer, a bit like no, no, do not worry about it.
- Claro (KLAH-roo) means of course, a very common way to agree.
- Isso (EE-soo) literally means that, and Brazilians use it to mean exactly, right, yes.
These small words carry a lot of everyday conversation. Claro and isso in particular will make your agreement sound natural, and they give you options so every yes is not a plain sim.
Formal versus casual replies
The words sim and nao themselves are neutral, so you can use them with anyone. What changes with formality is what you add around them.
- Polite yes: Sim, por favor (seeng, poor fah-VOR), yes, please.
- Polite no: Nao, obrigado if you are male or Nao, obrigada if you are female (nowng, oh-bree-GAH-doo or GAH-dah), no, thank you.
- Softer no: Infelizmente nao (unfortunately not).
Note that obrigado and obrigada change with the gender of the speaker, not the listener, which trips up a lot of learners. A man always says obrigado. Pairing your no with thanks is the standard polite refusal in both Brazil and Portugal.
The fastest progress comes from talking
Practice out loud with an AI coach that listens, corrects your pronunciation, and never makes you feel judged. That is how fluency actually builds.
Brazil and Portugal differences
The good news is that sim and nao are identical across both countries. The difference is mostly sound and rhythm.
- In Portugal, speech is faster and vowels get swallowed, so nao can sound clipped.
- In Brazil, the nasal vowels are often more open and drawn out.
- The verb-echo habit is strong in both, so Falo for yes works everywhere.
You do not need to pick a side to be understood. Whichever accent you learn, a Portuguese speaker from the other country will understand your yes and no without trouble. Focus on the nasal sounds first and let the accent come later.
Useful words near yes and no
Real conversations need more than two words. These fill the gaps between a hard yes and a hard no.
- Talvez (tal-VESS) means maybe.
- Acho que sim (AH-shoo kee seeng) means I think so.
- Acho que nao (AH-shoo kee nowng) means I do not think so.
- Tudo bem (TOO-doo beng) means all good, and often works as a soft yes or okay.
- Nem pensar (neng pen-SAR) means no way, a firm playful refusal.
Having a maybe and an I think so keeps you from forcing every answer into yes or no, which is what real people do. These phrases buy you time and sound natural while you find the rest of your sentence.
Common mistakes to avoid
A few errors show up again and again with English speakers.
- Flattening the nasal sounds. Sim is not seem and nao is not now. Let the air go through your nose.
- Choosing the wrong obrigado. Match it to your own gender, not the person you are talking to.
- Overusing bare sim. It is correct but stiff. Echo the verb or use claro and isso to sound relaxed.
- Forgetting that nao also negates verbs, so Eu nao sei means I do not know.
The fix for all of these is hearing yourself. Read the answers here aloud, or practice a short back and forth with a patient friend or an AI speaking partner, and the nasal sounds will settle in faster than silent study ever manages.

Frequently asked questions
How do you say yes in Portuguese?
Yes is sim (pronounced seeng with a nasal ending). In casual speech, people often answer by repeating the verb instead, for example Falo (I speak) to mean yes.
How do you say no in Portuguese?
No is nao (pronounced nowng, nasal). The same word goes before a verb to negate it, so Nao falo means I do not speak.
Is sim used the same way in Brazil and Portugal?
Yes, the words sim and nao are identical in both countries. Only the accent and rhythm differ, and speakers from either country will understand you.
How do I politely refuse something in Portuguese?
Say Nao, obrigado if you are male or Nao, obrigada if you are female, which means no, thank you. Match the word to your own gender.
Why do Portuguese speakers not always say sim?
In everyday conversation they often answer by echoing the verb of the question, which sounds more natural than a plain sim. You add nao before the verb for a no.
