Negation Overview

Making a Portuguese sentence negative is, in its simplest form, gloriously easy: you drop a single word — não — in front of the verb, and you are done. Falo português becomes Não falo português. Vou à praia becomes Não vou à praia. That one rule carries you through thousands of everyday sentences and is the first thing to internalise.

But Portuguese negation quickly becomes more interesting. The language uses double (and triple, and quadruple) negation as a matter of course: Não vi nada, Não vi ninguém, Não disse nada a ninguém nunca. Unlike in English, these negatives do not cancel each other out — they reinforce the negation. The language also has a symmetric system where negative words can appear without não, provided they come before the verb: Ninguém veio, Nunca o vi. And it has a small catalogue of emphatic strengtheners — Nem pensar!, De maneira nenhuma!, Nada disso! — that every learner eventually needs.

This page is the orienting tour. It lays out the basic architecture of Portuguese negation and points to the sibling pages where each piece is treated in depth.

The one-word rule: não before the verb

The core of Portuguese negation is a single adverb, não, placed immediately before the finite verb. There is no auxiliary (no do / does / did), no contracted form, no split between subject and verb — just não and then the verb.

That is the whole rule for basic negation. In questions, reported speech, subordinate clauses — everywhere — não sits right before the verb.

See the Basic Negation with Não page for the full treatment of não placement, including how it interacts with clitic pronouns, modal verbs, compound tenses, and estar a + infinitive.

Double negation is normal — and does not cancel

The single most important thing English speakers need to unlearn: in Portuguese, piling up negatives is standard, grammatical, and expected. Não vi nada does not mean "I didn't see nothing" in the sense of "I saw something." It means, simply, I saw nothing / I didn't see anything.

You can stack negatives further without it sounding odd:

The rule in one sentence: whenever a negative word comes after the verb, não is obligatory before the verb. Miss the não and the sentence is ungrammatical. Vi ninguém is not a Portuguese sentence; Não vi ninguém is.

See the Double Negation page for why this works, the full list of paired constructions (não... nada, não... ninguém, não... nunca, não... nem... nem...), and how to handle stacking.

Negative words without não — pre-verbal position

The counterpart rule: when the same negative word comes before the verb, não disappears. The verb is still flanked by exactly one negator — just on the other side.

You have a choice with objects and adverbials: put the negative word after the verb (and add não), or move it before the verb (and drop não). Both are grammatical; the pre-verbal version sounds slightly more formal or emphatic.

For subjects, however, the pre-verbal form is the natural order — the subject simply goes where subjects go.

See the Negation Without Não page for when to choose each word order, topicalised negatives, and literary fronting.

Position of não: right before the verb — and before clitics

Não attaches to the verb. If there is a clitic pronoun, não comes before the pronoun, and the pronoun goes before the verb (proclisis). Negation is one of the classic proclisis triggers in European Portuguese.

See Próclise Triggers for the full list of words that trigger pronoun-before-verb placement.

Modal and compound constructions — não on the finite verb

When there is a modal verb (poder, querer, dever, saber) plus an infinitive, não goes on the modal, not on the infinitive. Same for estar a + infinitive and for ter + past participle compound tenses.

Putting não on the infinitive is possible but means something different — it negates the infinitive itself as a nominalised action. Learners should stick with the finite-verb version at A1.

Negation with gostar de, precisar de, and other verbs with prepositions

Portuguese has a large set of verbs that require a preposition before their object — gostar de, precisar de, lembrar-se de, esquecer-se de, depender de. Negating these sentences does not touch the preposition; you simply add não in front of the verb as usual.

Tag questions: ..., não é? — and the verb-echo pattern

Portuguese tag questions are blissfully simple. The default universal tag is não é? — roughly "right? / isn't it?" — which works for any statement regardless of its verb or tense.

There is also a more specific pattern that echoes the verb itself, affirmative + negative: Ele vem, não vem? / Tu gostas, não gostas? / Ela sabe, não sabe? This is more emphatic and more personal than the generic não é? — it asks "come on, confirm this for me."

For negative statements, the tag flips: Ele não vem, pois não? or ... não é?.

Emphatic negation and strengtheners

When a plain não is not strong enough, Portuguese reaches for a set of short, punchy expressions. These are especially common in speech, where they carry rejection, disbelief, or refusal.

These are not abstract expressions — they are what Portuguese speakers actually say when they want to shut down a suggestion.

Negative responses to questions and offers

When someone offers you something and you want to decline politely, não on its own can feel terse. PT-PT has softer formulas:

Note the gender agreement in obrigado/obrigada — it's the thanker who agrees, not the person being thanked. A man says obrigado, a woman says obrigada, regardless of whom they are addressing.

Answering no and the verb-echo reply

Portuguese often answers yes-no questions by echoing the verb — especially to sim-type replies. For no-replies, the common pattern is Não followed by a repeated negated verb:

The doubled não, não... is not a mistake or hesitation — the first não answers the question, and the second negates the restated verb. Both are needed.

Common mistakes

Key takeaways

• Basic rule: não before the finite verb, and nothing else is needed. No auxiliary, no agreement.
• Double negation is the norm — Não vi nada means "I saw nothing." Multiple negatives reinforce, they do not cancel.
• Pre-verbal negative words drop the não — Ninguém veio, Nunca vi, Nada sei. The verb always has exactly one negator.
• Não goes before both the clitic and the verb: Não me viu. Negation is a classic proclisis trigger.
• In modal / compound / estar a structures, não attaches to the finite verb, not the infinitive or participle.
• Tag questions default to não é?; echoes of the verb (não vens?) are more emphatic.
• Emphatic negation: Nem pensar!, De maneira nenhuma!, Nada disso! — short, punchy, idiomatic.
