Negation and Clitic Placement | Portuguese (Portugal) Grammar

European Portuguese has one of the subtler clitic-placement systems in the Romance family. In neutral affirmative sentences, object pronouns attach after the verb — vejo-te, disse-me, lavaram-se — a pattern called ênclise. A small but important set of "triggers" flips this default, pulling the pronoun before the verb: próclise. Of all the triggers, the single most reliable one — the one every PT-PT learner must internalise before moving on — is negation.

This page covers the intersection. The core rule is short and unforgiving: whenever the clause is negated by não (or by a pre-verbal negative word), the pronoun goes in front of the verb, not behind it. We look at how this plays out across simple tenses, compound tenses, modal + infinitive constructions, the synthetic future (where negation actually breaks the otherwise-mesoclitic pattern), and coordination.

The core rule

When não precedes the verb, the clitic pronoun sits between não and the verb.

Não te vejo desde segunda-feira.

I haven't seen you since Monday.

Não me ligou ainda?

Hasn't he called you yet? / Hasn't he called me yet?

Não nos disseram nada sobre a mudança.

They didn't tell us anything about the change.

Não se lembra de ter prometido isso.

He doesn't remember having promised that.

Structurally: Não + clitic + verb. The three elements are ordered exactly this way, with nothing permitted between the clitic and the verb.

The affirmative-to-negative flip

The easiest way to see the rule is to watch a neutral enclitic pair flip to the proclitic pattern under negation.

Affirmative (ênclise)	Negative (próclise)	English
Vi-o ontem.	Não o vi ontem.	I saw / didn't see him yesterday.
Disse-me a verdade.	Não me disse a verdade.	He told / didn't tell me the truth.
Conhece-me há anos.	Não me conhece há anos.	He has known / hasn't known me for years.
Lavo-me de manhã.	Não me lavo de manhã.	I wash / don't wash (myself) in the morning.
Chamou-lhe um imbecil.	Não lhe chamou um imbecil.	He called / didn't call him a fool.
Deram-nos as chaves.	Não nos deram as chaves.	They gave / didn't give us the keys.

Notice the consistent pattern: the pronoun moves from after the verb (vi-o) to between não and the verb (não o vi). It never stays in the post-verbal slot when não is present.

Affirmative: Viu-me na rua. → Negative: Não me viu na rua.

He saw me / didn't see me on the street.

Affirmative: Contaram-lhe a história. → Negative: Não lhe contaram a história.

They told / didn't tell him the story.

Affirmative: Conheço-a há muito tempo. → Negative: Não a conheço há muito tempo.

I've known / haven't known her for a long time.

💡

If you remember only one clitic-placement rule from this guide, remember this one: não + clitic + verb. It is the single most reliable trigger in the language and comes up in roughly every third PT-PT sentence.

Combined clitics under negation

When two clitics combine (an indirect + direct object pair, producing forms like mo, ta, lho, no-lo), the whole cluster moves as a unit to the proclitic position.

Deu-me o livro. → Deu-mo.

He gave me the book. → He gave it to me.

Não me deu o livro. → Não mo deu.

He didn't give me the book. → He didn't give it to me.

Não lho disse, foi o Pedro.

I didn't tell it to him — it was Pedro.

Não no-lo explicaram com clareza.

They didn't explain it to us clearly.

Não ta vou oferecer, já te disse.

I'm not going to give it to you — I've already told you.

The combined clitic forms are taught in their own page; the point here is that negation does not change their internal shape, only their position.

Compound tenses: ter + particípio

Portuguese compound tenses use the auxiliary ter (or haver, in formal writing) + the past participle. When negation is added, não precedes the auxiliary, and the clitic sits between não and the auxiliary — not between the auxiliary and the participle.

Tinha-o visto antes. (affirmative) → Não o tinha visto antes.

I had seen him before. → I hadn't seen him before.

Não me tinha apercebido disso.

I hadn't realised that.

Não te tenho visto na faculdade ultimamente.

I haven't been seeing you at the university lately.

Não lhe tínhamos ligado antes da reunião.

We hadn't called him before the meeting.

Não nos terão reservado a mesa, afinal?

Won't they have reserved the table for us, after all?

The clitic never attaches to the participle in the compound tense. Forms like não tinha-o visto or não tinha visto-o are wrong in EP.

Estar a + infinitive — the progressive

European Portuguese uses estar a + infinitive where BR uses the gerund (estar fazendo). Under negation, não precedes estar, and the clitic climbs all the way to the front — in front of estar.

Estou a ouvir-te. (affirmative) → Não te estou a ouvir.

I'm listening to you. → I'm not listening to you.

Não me estás a dizer tudo o que sabes.

You're not telling me everything you know.

Não nos está a parecer uma boa ideia.

It's not seeming like a good idea to us.

Não se está a portar bem, é verdade.

He's not behaving well, it's true.

Não lhe estou a pedir nada de extraordinário.

I'm not asking him anything extraordinary.

The climb is obligatory — PT-PT prefers não te estou a ouvir over the alternative não estou a ouvir-te. The second is tolerated, especially in more formal written PT-PT and in BR, but in conversational EP it sounds slightly off.

💡

Clitic climbing under a trigger is the default. In não + auxiliary + gerund/infinitive constructions, expect the clitic to land in front of the auxiliary, not on the non-finite verb.

Modals (poder, querer, dever, ter de, ir) followed by an infinitive offer a genuine choice in neutral EP — either Posso dizer-te (enclisis on the infinitive) or Posso-te dizer (enclisis on the modal) are available. Under negation, EP overwhelmingly prefers proclisis on the modal:

Posso dizer-te a verdade. (neutral, affirmative) → Não te posso dizer a verdade.

I can tell you the truth. → I can't tell you the truth.

Não te posso emprestar o carro hoje.

I can't lend you the car today.

Não me quero envolver nisso.

I don't want to get involved in that.

Não lhe devia ter dito isso.

I shouldn't have told him that.

Não se deve mentir aos clientes.

One shouldn't lie to customers.

Não vos vamos esquecer.

We won't forget you (plural).

Não te tenho de explicar nada.

I don't have to explain anything to you.

The alternative não posso dizer-te (clitic stays on the infinitive) is also grammatical and appears in formal writing and in BR. In spoken PT-PT, though, the climbed version is the natural default — and a PT-PT tutor will generally correct a learner who leaves the clitic on the infinitive.

The synthetic future and conditional: negation breaks mesóclise

One of the most distinctive patterns of European Portuguese is mesóclise — the placement of a clitic inside a synthetic future or conditional form: ver-te-ei ("I will see you"), dir-lhe-ia ("I would tell him"). Mesóclise is a literary and formal pattern but still very much alive in written EP.

Under negation, mesóclise breaks. The clitic exits the interior of the verb and moves to the proclitic position in front of the (now intact) synthetic form.

Without negation (mesóclise)	With negation (próclise)	English
Ver-te-ei amanhã.	Não te verei amanhã.	I will (not) see you tomorrow.
Dir-lhe-ei a verdade.	Não lhe direi a verdade.	I will (not) tell him the truth.
Dir-te-ia, se pudesse.	Não te diria, mesmo que pudesse.	I would (not) tell you, if I could.
Convidar-nos-ão?	Não nos convidarão?	Will they (not) invite us?
Ajudá-lo-ia com gosto.	Não o ajudaria, depois do que fez.	I would (not) help him with pleasure. / not, after what he did.

The reason is straightforward: mesóclise is the default clitic position in the future/conditional only when no trigger is present. As soon as negation enters the clause, it forces proclisis, the clitic moves out of the verb, and the future/conditional reassembles into a single unit.

Não te esquecerei nunca.

I will never forget you.

Não me diria o que aconteceu.

He wouldn't tell me what happened.

Não lhes explicaríamos sem mais contexto.

We wouldn't explain it to them without more context.

Não se contentaria com menos.

He wouldn't settle for less.

Writing não te-ver-ei or não-ver-te-ei is wrong — the clitic must exit mesóclise entirely. This is one of the clearest tests of PT-PT clitic competence.

💡

Mesóclise lives in conditional/future tenses unless a trigger is present. Negation, like any other trigger, dissolves mesóclise and re-forms the synthetic verb into a single word.

Negative words other than não

The trigger isn't just não. Any pre-verbal negative word — nunca, jamais, nada, ninguém, nenhum, nem — triggers proclisis exactly like não. Remember: pre-verbal negative words don't take an additional não (that's the double-negation rule).

Nunca te esquecerei.

I will never forget you.

Jamais lhe direi o que aconteceu.

I will never tell him what happened.

Nada me assusta neste momento.

Nothing frightens me at this moment.

Ninguém nos viu sair da sala.

Nobody saw us leave the room.

Nenhum dos convidados se queixou da comida.

None of the guests complained about the food.

Nem me imagino o susto que ela apanhou.

I can't even imagine the fright she got.

Nem se dignou responder ao meu email.

He didn't even deign to reply to my email.

Each of these negative words is a trigger in its own right. The double negation only appears when the negative word is post-verbal, in which case não precedes the verb and the negative word follows:

Não vi ninguém. (double negation, ninguém post-verbal)

I saw nobody. / I didn't see anybody.

Ninguém me viu. (single negation, ninguém pre-verbal)

Nobody saw me.

Notice that in both versions the clitic is proclitic: in the first the trigger is não; in the second the trigger is ninguém. Pre-verbal negatives always trigger proclisis, whether não is present or not.

Interaction with other triggers

Negation is a trigger; so are subordinators (que, se, quando, porque), relatives (que, quem, onde), interrogatives (quem, o que, onde), indefinite subjects (alguém, todos, muitos), and a small closed set of proclitic adverbs (já, ainda, sempre, só, também, talvez). When negation combines with one of these, they stack — proclisis is reinforced, not cancelled.

Disse que não me ligava hoje.

He said he wouldn't call me today. (que + não)

Se não te apetecer, não venhas.

If you don't feel like it, don't come. (se + não)

Quando não se sabe o que fazer, é melhor esperar.

When one doesn't know what to do, it's better to wait. (quando + não)

A única pessoa que não me tinha telefonado foi o João.

The only person who hadn't called me was João. (que + não + compound tense)

Porque não te disse nada antes?

Why didn't he say anything to you before? (porque + não)

Ninguém que nunca o tenha conhecido pode dizer isso.

Nobody who's never met him can say that. (ninguém + que + nunca)

Two independent triggers do not "cancel" each other. Both force proclisis. The result is a doubly-marked proclitic environment.

Coordination: what happens at e, mas, ou

Coordination with e, mas, ou starts a new clause. Triggers in the first clause do not reach into the second. If the second clause has no trigger, ênclise is restored.

Não o vi ontem, mas encontrei-o hoje.

I didn't see him yesterday, but I ran into him today.

Não te liguei à tarde, e telefonei-te à noite.

I didn't call you in the afternoon, and I called you in the evening.

Não me avisaram, ou esqueceram-se de todo.

They didn't warn me, or they forgot entirely.

In each example, the first clause is proclitic (trigger: não), and the second reverts to enclitic because it has no trigger of its own. This is one of the most subtle but most important coordination rules in PT-PT.

If the second clause does carry a trigger of its own — a subordinator, a negative word, a proclitic adverb — then it stays proclitic:

Não o vi ontem, mas nunca o tinha visto antes.

I didn't see him yesterday, but I had never seen him before. (second clause: trigger 'nunca')

Não te liguei à tarde, e também não te ligo agora.

I didn't call you in the afternoon, and I'm not calling you now either. (second clause: trigger 'também não')

When não is not clause-initial

In some spoken and poetic styles, a left-dislocated topic precedes não. The clitic still sits in front of the verb, between não and the verb — the topic doesn't change the rule.

A verdade, não a posso dizer agora.

The truth, I can't tell it now.

Esse livro, não o li todo, confesso.

That book, I haven't read it all, I confess.

Daquele filme, não me lembro quase nada.

Of that film, I remember almost nothing.

The topic is set off by a comma; the proclitic structure inside the main clause is preserved.

Imperatives and não — the "don't!" form

The negative imperative uses the subjunctive form of the verb — and because não is present, proclisis applies there too. Note how this contrasts with the affirmative imperative, which takes the imperative form and enclitic pronouns.

Affirmative command	Negative command	English
Conta-me tudo!	Não me contes nada!	Tell me everything! / Don't tell me anything!
Diz-lhe a verdade.	Não lhe digas a verdade.	Tell him the truth. / Don't tell him the truth.
Senta-te aqui.	Não te sentes aí.	Sit here. / Don't sit there.
Ajuda-o.	Não o ajudes.	Help him. / Don't help him.
Dêem-nos mais tempo.	Não nos deem mais problemas.	Give us more time. / Don't give us any more problems.

The shift is doubly marked: the verb form changes (imperative → subjunctive), and the clitic moves (enclitic → proclitic). Both changes are triggered by não.

Senta-te ao pé de mim. → Não te sentes ao pé de mim, estou com frio.

Sit next to me. → Don't sit next to me, I'm cold.

Diz-me o teu nome. → Não me digas nada, quero adivinhar.

Tell me your name. → Don't tell me anything, I want to guess.

Reference table: the six key environments

Environment	Example (affirmative)	Example (negative)
Simple tense	Viu-me.	Não me viu.
Compound tense	Tinha-o visto.	Não o tinha visto.
Estar a + infinitive	Estou a ouvir-te.	Não te estou a ouvir.
Modal + infinitive	Posso dizer-te. / Posso-te dizer.	Não te posso dizer. (preferred)
Synthetic future/cond.	Ver-te-ei. / Dir-lhe-ia.	Não te verei. / Não lhe diria.
Imperative	Diz-lhe!	Não lhe digas!

Common mistakes

❌ Não vi-o ontem.

Incorrect — *não* triggers proclisis. The pronoun must precede the verb.

✅ Não o vi ontem.

I didn't see him yesterday.

❌ Não tinha visto-o antes.

Incorrect — the clitic must be before the auxiliary in a negated compound tense.

✅ Não o tinha visto antes.

I hadn't seen him before.

❌ Não estou a ouvir-te.

Acceptable but dispreferred in PT-PT — the trigger pulls the clitic all the way to the front.

✅ Não te estou a ouvir.

I'm not listening to you. (preferred PT-PT form)

❌ Não te-ver-ei amanhã. / Não ver-te-ei amanhã.

Incorrect — mesóclise dissolves under negation; the synthetic form must be intact with the clitic in front.

✅ Não te verei amanhã.

I will not see you tomorrow.

❌ Ninguém não me viu.

Incorrect — pre-verbal negative subjects (*ninguém, nada, nenhum*) don't take an additional *não*.

✅ Ninguém me viu.

Nobody saw me.

❌ Não o vi ontem, mas o encontrei hoje.

Incorrect — a coordinating *mas* starts a new clause. Without its own trigger, the second clause reverts to ênclise.

✅ Não o vi ontem, mas encontrei-o hoje.

I didn't see him yesterday, but I ran into him today.

❌ Não senta-te aí. / Não te senta aí.

Two errors — negative commands use the subjunctive form and proclisis. The correct verb form is *sentes*, with the clitic in front.

✅ Não te sentes aí.

Don't sit there.

❌ Não dás-me o livro?

Incorrect — even in a question, *não* triggers proclisis.

✅ Não me dás o livro?

Won't you give me the book?

Key takeaways

Não is the most reliable proclisis trigger in European Portuguese. Every time you see a pre-verbal não, expect the pronoun in front of the verb: não + clitic + verb.
The rule extends to all pre-verbal negatives: nunca, jamais, nada, ninguém, nenhum, nem.
In compound tenses, the clitic sits in front of the auxiliary: não o tinha visto, not não tinha-o visto.
In estar a
infinitive
and modal + infinitive, EP prefers clitic climbing — the clitic moves to the front of the auxiliary or modal: não te estou a ouvir, não te posso dizer.
Mesóclise dissolves under negation: ver-te-ei → não te verei. The synthetic form stays intact; the clitic moves out.
Coordination breaks the trigger: a second clause joined by e, mas, ou gets a fresh start. Without its own trigger, it reverts to ênclise.
In negative imperatives, both the verb form changes (imperative → subjunctive) and the clitic moves (enclitic → proclitic): diz-me → não me digas.
When in doubt, say the sentence aloud. Não vi-o sounds wrong to a native ear; não o vi is the only natural rhythm.
