Beginners learn negation as "stick não in front of the verb", and that does cover most cases. But Brazilian Portuguese negates in several ways that involve no não at all. Recognising them matters for two reasons: you will misread sentences if you expect não to be the only signal of negation, and your own Portuguese will sound stiff if não is the only tool you reach for. This page collects the main não-free negators.
1. A negative word in front of the verb
The most important case is the one introduced on the negative-words page: when a negative word (ninguém, nada, nunca, nenhum, nem) sits before the verb, it carries the negation alone, and não must not appear.
Ninguém apareceu na reunião.
Nobody showed up at the meeting.
Nada mudou desde então.
Nothing has changed since then.
Nunca mais falo com ele.
I'll never speak to him again.
Nenhum dos meus amigos veio.
None of my friends came.
The logic is economy: the fronted negative word already occupies the "negation slot" at the head of the clause, so a second não would be redundant — and Portuguese, unlike its own post-verbal concord, refuses the redundancy here. English has no comparable rule because English never lets the negative indefinite take over the auxiliary's job ("Nobody came", not "Nobody didn't come").
2. "Sem" — negation of nouns and infinitives
Sem means "without" and is the workhorse for negating a noun or an action without touching the main verb. It is the natural opposite of com (with).
Eu tomo café sem açúcar.
I drink coffee without sugar.
Ela saiu sem falar com ninguém.
She left without speaking to anyone.
Cheguei em casa sem as chaves.
I got home without my keys.
Two things to notice. First, sem + infinitive corresponds to English "without …-ing": sem falar = "without speaking". English speakers reach for a gerund there; Portuguese uses the plain infinitive. Second, after sem you still use negative words (sem falar com ninguém), because the clause is semantically negative — concord again. See the dedicated preposition page for more on sem.
Resolvi tudo sem ajuda de ninguém.
I sorted everything out with nobody's help.
3. "Nem" — "not even" / "nor"
Nem packs "and not", "nor", or "not even" into one word, and at the head of a clause it negates without não.
Nem liguei pra ela ainda.
I haven't even called her yet.
Nem sei o que dizer.
I don't even know what to say.
Nem sei / nem sabia ("I don't even know / didn't even know") is a fixed conversational opener. Because nem sits before the verb, there is no não. (The full range of nem — including nem… nem and nem que — has its own page.)
4. Negative prefixes
You can bake negation straight into a word with a prefix, so the sentence verb stays positive. The big two are in- (and its variants im-/i-/ir-) and des-.
Isso é totalmente impossível.
That's completely impossible.
Ele foi muito desonesto comigo.
He was very dishonest with me.
Pode desligar a TV, por favor?
Can you turn off the TV, please?
Here impossível, desonesto and desligar are negative in themselves — the verbs é, foi, pode are perfectly affirmative. This lets you negate a single concept rather than the whole clause. The prefixes have their own page with the assimilation rules; the point for now is that prefixation is a genuine, very common negation strategy.
5. Lexical negatives — verbs that already mean "not"
Some verbs carry negation in their meaning, so you negate an idea without any negative morpheme at all. The most useful:
- deixar de + infinitive — to stop / quit doing
- parar de + infinitive — to stop doing
- faltar — to be missing / lacking
- evitar — to avoid
- deixar de can also mean "fail to"
Deixei de fumar no ano passado.
I quit smoking last year.
Falta sal nessa comida.
This food is lacking salt.
A gente evitou o assunto a noite toda.
We avoided the subject all night.
Note how deixei de fumar means "I no longer smoke" with zero negative words — the negation lives inside deixar de. English does the same thing with "quit" and "stop", so this one is intuitive; the trap is choosing the right verb (deixar de vs parar de — deixar de tends to mean a definitive, often permanent end, while parar de can be momentary).
Para de falar e me escuta!
Stop talking and listen to me!
6. "Longe de" and other phrasal negators
A few set phrases negate by implication. Longe de (far from) is the classic: longe de mim + verb signals strong denial.
Longe de mim criticar você, mas...
Far be it from me to criticise you, but...
This is (formal/literary)-leaning but appears in careful speech. It negates the speaker's intention without a single não.
7. Rhetorical negation
Questions can negate. A rhetorical question expecting "no" works as a denial: Quem liga? ("Who cares?" = nobody does). And expressions like que nada! dismiss a proposition entirely. These belong to the rhetorical-negation page, but flag them here so you recognise that a sentence with no não and even no negative word can still be a negation.
Common Mistakes
❌ Ninguém não veio.
Incorrect — a fronted 'ninguém' already negates; 'não' is forbidden here.
✅ Ninguém veio.
Nobody came.
This is the number-one error: importing the post-verbal concord rule into the pre-verbal slot.
❌ Ela saiu sem falando.
Incorrect — 'sem' takes the infinitive, not the gerund.
✅ Ela saiu sem falar.
She left without speaking.
English "without speaking" pushes you toward the -ndo form, but Portuguese pairs sem with the plain infinitive.
❌ Eu não deixei de não fumar.
Incorrect — 'deixar de' already means 'stop'; the extra 'não' reverses the sense.
✅ Deixei de fumar.
I stopped smoking.
Because deixar de is itself a negator, adding não flips you back to "I didn't stop smoking" — usually not what you mean.
❌ Tomo café sem nenhum açúcar não.
Awkward — stacking 'sem', 'nenhum' and final 'não' over-negates a simple idea.
✅ Tomo café sem açúcar.
I drink coffee without sugar.
Sem already negates; you rarely need to reinforce it. (The sentence is not strictly ungrammatical in very colloquial speech, but it sounds clumsy.)
❌ Falta de sal nessa comida.
Incorrect as a clause — 'faltar' is a verb here, so no 'de'.
✅ Falta sal nessa comida.
This food needs salt.
Don't confuse the verb faltar (to be lacking) with the noun phrase falta de (a lack of).
Key Takeaways
- Não is not the only negator. BR negates with fronted negative words, sem, nem, negative prefixes, and lexical verbs like deixar de / parar de / faltar / evitar.
- A negative word in front of the verb carries the negation alone — no não.
- sem + infinitive = English "without …-ing".
- Lexical negatives already contain "not", so adding não over-negates.
- When reading, look past não: a sentence can be negative with no não in sight.
