agir — Portuguese conjugation
to act
Indicative
Present (Presente) Irregular
The presente covers routines, states, and immediate future with adverbs like hoje or amanhã. One present form covers both English simple and progressive readings in most situations.
Ela estuda português todas as noites.
| Pronoun | Portuguese | English |
|---|---|---|
| eu | ajo | I act |
| tu | ages | you act |
| você | age | you act |
| ele/ela | age | he/she/it acts |
| nós | agimos | we act |
| vós | agis | you (pl.) act |
| vocês | agem | you (pl.) act |
| eles/elas | agem | they act |
Preterite (Pretérito perfeito simples) Regular
The pretérito perfeito simples is a sharp, completed past. In European Portuguese it is the standard story-telling past; Brazilian usage often prefers the compound form in speech while keeping the simple for narrative and writing.
Ontem escreveu a carta inteira de uma vez.
| Pronoun | Portuguese | English |
|---|---|---|
| eu | agi | I acted |
| tu | agiste | you acted |
| você | agiu | you acted |
| ele/ela | agiu | he/she/it acted |
| nós | agimos | we acted |
| vós | agistes | you (pl.) acted |
| vocês | agiram | you (pl.) acted |
| eles/elas | agiram | they acted |
Imperfect (Pretérito imperfeito) Regular
The imperfeito describes past background, repeated actions, and how things used to be. Contrast it with the simple preterite for the “main event” line of a story.
Quando era criança, brincava na praia.
| Pronoun | Portuguese |
|---|---|
| eu | agia |
| tu | agias |
| você | agia |
| ele/ela | agia |
| nós | agíamos |
| vós | agíeis |
| vocês | agiam |
| eles/elas | agiam |
Conditional (Condicional) Regular
The condicional is for polite offers, soft questions, and hypothetical “would” outcomes, and it often closes a se + imperfeito do subjuntivo chain in formal style.
Você poderia me explicar outra vez?
| Pronoun | Portuguese | English |
|---|---|---|
| eu | agiria | I would act |
| tu | agirias | you would act |
| você | agiria | you would act |
| ele/ela | agiria | he/she/it would act |
| nós | agiríamos | we would act |
| vós | agiríeis | you (pl.) would act |
| vocês | agiriam | you (pl.) would act |
| eles/elas | agiriam | they would act |
Future (Futuro do presente) Regular
The futuro do presente states future facts; in everyday conversation you will often hear ir + infinitive or even the present with a time adverb instead of the synthetic future.
Amanhã faremos a reunião mais cedo.
| Pronoun | Portuguese | English |
|---|---|---|
| eu | agirei | I will act |
| tu | agirás | you will act |
| você | agirá | you will act |
| ele/ela | agirá | he/she/it will act |
| nós | agiremos | we will act |
| vós | agireis | you (pl.) will act |
| vocês | agirão | you (pl.) will act |
| eles/elas | agirão | they will act |
Present perfect (Pretérito perfeito composto) Regular
The pretérito perfeito composto uses ter or haver plus the participle for a past that still touches the present or happens repeatedly up to now — a “have done” perfect with strong links to European norms.
Tenho pensado nisso há semanas.
| Pronoun | Portuguese | English |
|---|---|---|
| eu | tenho agido | I have acted |
| tu | tens agido | you have acted |
| você | tem agido | you have acted |
| ele/ela | tem agido | he/she/it has acted |
| nós | temos agido | we have acted |
| vós | tendes agido | you (pl.) have acted |
| vocês | têm agido | you (pl.) have acted |
| eles/elas | têm agido | they have acted |
Pluperfect (Mais-que-perfeito composto) Regular
The mais-que-perfeito composto is the pluperfect: an action was already finished before another past reference. It mirrors the English “had already”.
Já tinham saído quando chegámos.
| Pronoun | Portuguese | English |
|---|---|---|
| eu | tinha agido | I had acted |
| tu | tinhas agido | you had acted |
| você | tinha agido | you had acted |
| ele/ela | tinha agido | he/she/it had acted |
| nós | tínhamos agido | we had acted |
| vós | tínheis agido | you (pl.) had acted |
| vocês | tinham agido | you (pl.) had acted |
| eles/elas | tinham agido | they had acted |
Conditional perfect (Condicional composto) Regular
The condicional composto expresses a counterfactual “would have” and appears with the right kind of if-clause in the subjunctive past for unreal conditions.
Teria aceite se tiveses avisado com antecedência.
| Pronoun | Portuguese |
|---|---|
| eu | teria agido |
| tu | terias agido |
| você | teria agido |
| ele/ela | teria agido |
| nós | teríamos agido |
| vós | teríeis agido |
| vocês | teriam agido |
| eles/elas | teriam agido |
Future perfect (Futuro composto) Regular
The futuro composto is the future-in-the-future: something will be finished before a later time. It is less frequent than the simple future but still useful for deadlines.
Até sexta, teremos lido tudo o relatório.
| Pronoun | Portuguese | English |
|---|---|---|
| eu | terei agido | I will have acted |
| tu | terás agido | you will have acted |
| você | terá agido | you will have acted |
| ele/ela | terá agido | he/she/it will have acted |
| nós | teremos agido | we will have acted |
| vós | tereis agido | you (pl.) will have acted |
| vocês | terão agido | you (pl.) will have acted |
| eles/elas | terão agido | they will have acted |
Subjunctive
Present subjunctive (Conjuntivo presente) Regular
The present subjunctive appears after want, hope, fear, and impersonal triggers, and typically requires a new subject in the subordinate clause, just as in the other main Romance languages.
Espero que encontres o caminho fácil.
| Pronoun | Portuguese |
|---|---|
| eu | aja |
| tu | ajas |
| você | aja |
| ele/ela | aja |
| nós | ajamos |
| vós | ajais |
| vocês | ajam |
| eles/elas | ajam |
Imperfect subjunctive (Conjuntivo pretérito imperf.) Regular
The imperfect subjunctive in se + subjunctive → condicional is the classic “if I were a rich man” line in European Portuguese, parallel to the Spanish -ra form.
Se tivesse mais tempo, aprenderia outro idioma.
| Pronoun | Portuguese |
|---|---|
| eu | agisse |
| tu | agisses |
| você | agisse |
| ele/ela | agisse |
| nós | agíssemos |
| vós | agísseis |
| vocês | agissem |
| eles/elas | agissem |
Other forms
Imperative (affirmative) (Imperativo afirmativo) Regular
The affirmative imperative in Portuguese is built with tu, você, nós, vós, and vocês forms; Brazilian norms favour você/vocês with third-person present verb shapes.
Diga a verdade, por favor.
| Pronoun | Portuguese |
|---|---|
| tu | age |
| você | aja |
| ele/ela | aja |
| nós | ajamos |
| vós | agi |
| vocês | ajam |
| eles/elas | ajam |
Imperative (negative) (Imperativo negativo) Regular
Negative commands require não plus the present subjunctive for each person, which is a distinctive feature compared to other Romance systems that reuse present indicative in some slots.
Não falemos com pressa, está tudo calmo.
| Pronoun | Portuguese |
|---|---|
| tu | não ajas |
| você | não aja |
| ele/ela | não aja |
| nós | não ajamos |
| vós | não ajais |
| vocês | não ajam |
| eles/elas | não ajam |
