Conditional Perfect — Habría hecho

By the end of this lesson, you will be able to form and use the conditional perfect (habría + past participle) to talk about what would have happened in hypothetical past situations, and distinguish it from the simple conditional.

Introduction

You already know the simple conditional (hablaría — I would speak) for polite requests and hypothetical situations. Now imagine you want to say "I would have spoken" — referring not just to what might happen, but to what would have happened in a past that never occurred. That is the conditional perfect (condicional compuesto), and it is the result clause in the most powerful conditional sentences in Spanish: Si hubiera sabido la verdad, te lo habría dicho. Mastering it unlocks the full range of speculation about the past.

Core Concept

Formation

Conditional perfect = conditional of haber + past participle

Pronoun	haber conditional	Example with hacer
yo	habría	habría hecho
tú	habrías	habrías hecho
él/ella/Ud.	habría	habría hecho
nosotros	habríamos	habríamos hecho
vosotros	habríais	habríais hecho
ellos/Uds.	habrían	habrían hecho

Past participles follow the same rules as in the present perfect — irregular ones (hecho, dicho, escrito, visto, puesto, vuelto, roto, abierto, cubierto, muerto) must be memorized.

When to Use It

The conditional perfect expresses an action that would have occurred in the past under a condition that was not met:
