Description

An Overview of the Conditional Perfect (Condicional Composto)

The conditional perfect is used to describe actions that would have happened under certain conditions, but did not occur:

  • Já teríamos saído, mas tivemos de esperar pela minha irmã.

  • Se tivesse dinheiro suficiente, teria comprado um carro.


Meaning and Use

The conditional perfect expresses:

  • unrealized past situations

  • hypothetical outcomes

  • meanings like “would have”, “could have”, or “should have”

👉 In these cases, the condition was not fulfilled, so the action did not take place.


Use with se ("if" clauses)

Like the present conditional, the conditional perfect is not used directly after se.

Instead:

  • se + imperfect subjunctivese tivesse dinheiro

  • main clause (conditional perfect)teria comprado

Example:

  • Teria ido contigo ao cinema se não fosse pelo exame.


How to Form the Conditional Perfect

The conditional perfect is formed using the conditional of ter + the past participle:

Subject Conditional Perfect Translation
eu teria falado I would have spoken
tu terias falado you would have spoken
ele/ela/você teria falado he/she would have spoken
nós teríamos falado we would have spoken
vocês/eles teriam falado they would have spoken

🔑 Key point

The conditional perfect expresses:

  • past actions that did not happen

  • due to unmet conditions

Questions

Questions about the Conditional Perfect (Portuguese)

Q: Why is it Se tivéssemos ido ao médico, ter-nos-íamos sentido melhor and NOT Se teríamos ido ao médico, tivéssemos sentido melhor?
When using this structure, the roles are fixed:

  • se clause (subordinate clause)past perfect subjunctive

  • main clauseconditional perfect

So:

  • Se tivéssemos ido ao médico, → correct (subjunctive after se)

  • ter-nos-íamos sentido melhor. → correct (conditional perfect in main clause)

Se teríamos ido… (never use the conditional after se)
… tivéssemos sentido melhor (wrong clause for subjunctive)


🔑 Key point

  • After se → always past perfect subjunctive (tivesse feito)

  • Main clause → conditional perfect (teria feito)

Exercises

Provide the conditional perfect (condicional composto) for the following subjects and verbs:

Ela (amar).
Nós (vir).
Tu (ter).
Vocês (estar).

---

Conjugate the verbs in each clause in the conditional perfect or the past subjunctive. Remember: the conditional perfect is used in the MAIN clause, NOT after se:

Se o meu pai (chegar) a tempo, não (esperar, nós) tanto tempo.
Tu (tirar) melhores notas se não (esquecer) a importância de estudar.
Os estudantes (dizer) isso se o professor não (fazer) o exame tão difícil.
