Indicative

Present (Presente) Regular

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.

PronounPortugueseEnglish
euinvestigoI investigate
tuinvestigasyou investigate
vocêinvestigayou investigate
ele/elainvestigahe/she/it investigates
nósinvestigamoswe investigate
vósinvestigaisyou (pl.) investigate
vocêsinvestigamyou (pl.) investigate
eles/elasinvestigamthey investigate

Preterite (Pretérito perfeito simples) Irregular

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.

PronounPortugueseEnglish
euinvestigueiI investigated
tuinvestigasteyou investigated
vocêinvestigouyou investigated
ele/elainvestigouhe/she/it investigated
nósinvestigamoswe investigated
vósinvestigastesyou (pl.) investigated
vocêsinvestigaramyou (pl.) investigated
eles/elasinvestigaramthey investigated

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.

PronounPortuguese
euinvestigava
tuinvestigavas
vocêinvestigava
ele/elainvestigava
nósinvestigávamos
vósinvestigáveis
vocêsinvestigavam
eles/elasinvestigavam

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?

PronounPortugueseEnglish
euinvestigariaI would investigate
tuinvestigariasyou would investigate
vocêinvestigariayou would investigate
ele/elainvestigariahe/she/it would investigate
nósinvestigaríamoswe would investigate
vósinvestigaríeisyou (pl.) would investigate
vocêsinvestigariamyou (pl.) would investigate
eles/elasinvestigariamthey would investigate

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.

PronounPortugueseEnglish
euinvestigareiI will investigate
tuinvestigarásyou will investigate
vocêinvestigaráyou will investigate
ele/elainvestigaráhe/she/it will investigate
nósinvestigaremoswe will investigate
vósinvestigareisyou (pl.) will investigate
vocêsinvestigarãoyou (pl.) will investigate
eles/elasinvestigarãothey will investigate

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.

PronounPortugueseEnglish
eutenho investigadoI have investigated
tutens investigadoyou have investigated
vocêtem investigadoyou have investigated
ele/elatem investigadohe/she/it has investigated
nóstemos investigadowe have investigated
vóstendes investigadoyou (pl.) have investigated
vocêstêm investigadoyou (pl.) have investigated
eles/elastêm investigadothey have investigated

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.

PronounPortugueseEnglish
eutinha investigadoI had investigated
tutinhas investigadoyou had investigated
vocêtinha investigadoyou had investigated
ele/elatinha investigadohe/she/it had investigated
nóstínhamos investigadowe had investigated
vóstínheis investigadoyou (pl.) had investigated
vocêstinham investigadoyou (pl.) had investigated
eles/elastinham investigadothey had investigated

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.

PronounPortuguese
euteria investigado
tuterias investigado
vocêteria investigado
ele/elateria investigado
nósteríamos investigado
vósteríeis investigado
vocêsteriam investigado
eles/elasteriam investigado

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.

PronounPortugueseEnglish
euterei investigadoI will have investigated
tuterás investigadoyou will have investigated
vocêterá investigadoyou will have investigated
ele/elaterá investigadohe/she/it will have investigated
nósteremos investigadowe will have investigated
vóstereis investigadoyou (pl.) will have investigated
vocêsterão investigadoyou (pl.) will have investigated
eles/elasterão investigadothey will have investigated

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.

PronounPortuguese
euinvestigue
tuinvestigues
vocêinvestigue
ele/elainvestigue
nósinvestiguemos
vósinvestigueis
vocêsinvestiguem
eles/elasinvestiguem

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.

PronounPortuguese
euinvestigasse
tuinvestigasses
vocêinvestigasse
ele/elainvestigasse
nósinvestigássemos
vósinvestigásseis
vocêsinvestigassem
eles/elasinvestigassem

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.

PronounPortuguese
tuinvestiga
vocêinvestigue
ele/elainvestigue
nósinvestiguemos
vósinvestigai
vocêsinvestiguem
eles/elasinvestiguem

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.

PronounPortuguese
tunão investigues
vocênão investigue
ele/elanão investigue
nósnão investiguemos
vósnão investigueis
vocêsnão investiguem
eles/elasnão investiguem
