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.

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

vocêdiagnosticouyou diagnosed
ele/eladiagnosticouhe/she/it diagnosed

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
eudiagnosticava
tudiagnosticavas
vocêdiagnosticava
ele/eladiagnosticava
nósdiagnosticávamos
vósdiagnosticáveis
vocêsdiagnosticavam
eles/elasdiagnosticavam

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
eudiagnosticariaI would diagnose
tudiagnosticariasyou would diagnose
vocêdiagnosticariayou would diagnose
ele/eladiagnosticariahe/she/it would diagnose
nósdiagnosticaríamoswe would diagnose
vósdiagnosticaríeisyou (pl.) would diagnose
vocêsdiagnosticariamyou (pl.) would diagnose
eles/elasdiagnosticariamthey would diagnose

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
eudiagnosticareiI will diagnose
tudiagnosticarásyou will diagnose
vocêdiagnosticaráyou will diagnose
ele/eladiagnosticaráhe/she/it will diagnose
nósdiagnosticaremoswe will diagnose
vósdiagnosticareisyou (pl.) will diagnose
vocêsdiagnosticarãoyou (pl.) will diagnose
eles/elasdiagnosticarãothey will diagnose

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 diagnosticadoI have diagnosed
tutens diagnosticadoyou have diagnosed
vocêtem diagnosticadoyou have diagnosed
ele/elatem diagnosticadohe/she/it has diagnosed
nóstemos diagnosticadowe have diagnosed
vóstendes diagnosticadoyou (pl.) have diagnosed
vocêstêm diagnosticadoyou (pl.) have diagnosed
eles/elastêm diagnosticadothey have diagnosed

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 diagnosticadoI had diagnosed
tutinhas diagnosticadoyou had diagnosed
vocêtinha diagnosticadoyou had diagnosed
ele/elatinha diagnosticadohe/she/it had diagnosed
nóstínhamos diagnosticadowe had diagnosed
vóstínheis diagnosticadoyou (pl.) had diagnosed
vocêstinham diagnosticadoyou (pl.) had diagnosed
eles/elastinham diagnosticadothey had diagnosed

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 diagnosticado
tuterias diagnosticado
vocêteria diagnosticado
ele/elateria diagnosticado
nósteríamos diagnosticado
vósteríeis diagnosticado
vocêsteriam diagnosticado
eles/elasteriam diagnosticado

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 diagnosticadoI will have diagnosed
tuterás diagnosticadoyou will have diagnosed
vocêterá diagnosticadoyou will have diagnosed
ele/elaterá diagnosticadohe/she/it will have diagnosed
nósteremos diagnosticadowe will have diagnosed
vóstereis diagnosticadoyou (pl.) will have diagnosed
vocêsterão diagnosticadoyou (pl.) will have diagnosed
eles/elasterão diagnosticadothey will have diagnosed

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
eudiagnostique
tudiagnostiques
vocêdiagnostique
ele/eladiagnostique
nósdiagnostiquemos
vósdiagnostiqueis
vocêsdiagnostiquem
eles/elasdiagnostiquem

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
eudiagnosticasse
tudiagnosticasses
vocêdiagnosticasse
ele/eladiagnosticasse
nósdiagnosticássemos
vósdiagnosticásseis
vocêsdiagnosticassem
eles/elasdiagnosticassem

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
tudiagnostica
vocêdiagnostique
ele/eladiagnostique
nósdiagnostiquemos
vósdiagnosticai
vocêsdiagnostiquem
eles/elasdiagnostiquem

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 diagnostiques
vocênão diagnostique
ele/elanão diagnostique
nósnão diagnostiquemos
vósnão diagnostiqueis
vocêsnão diagnostiquem
eles/elasnão diagnostiquem
