Conditional Perfect: Expressing Hypothetical Past Actions
What You'll Learn
Overview / Usage
The conditional perfect (condicional perfecto or condicional compuesto) expresses actions that would have happened in the past under different circumstances. It's formed with the conditional tense of haber + past participle.
This advanced tense is essential for expressing regret, speculation about the past, and hypothetical situations:
- Regret or unfulfilled actions: "I would have gone" (habría ido)
- Speculation about the past: "He would have been about 30" (habría tenido unos 30 años)
- Conditional sentences: "If I had known, I would have helped" (Si hubiera sabido, habría ayudado)
- Polite speculation: "It would have been around 8pm" (habrían sido las ocho)
💡 When to Use Conditional Perfect
Use conditional perfect when talking about what would have happened if circumstances had been different. It often appears in "if" clauses (if I had known..., I would have...) and expressions of regret or missed opportunities.
