Condicional Compuesto
The conditional compound (also called conditional perfect) in Spanish is used exactly the same way as "would have" in English. If you would say "would have" in English, you use the conditional compound in Spanish. It's used to express what you would have done under certain circumstances, talk about hypothetical situations in the past, express regrets, and make suppositions about past events.
In English, we use "would have" + past participle ("I would have eaten"). In Spanish, we use habría (haber in conditional) + past participle. It works in exactly the same way!
The conditional compound is a combination of the Perfect Tense and the Conditional. It's very simple: conjugate "haber" in the conditional simple, then add the past participle!

Important: The irregular past participles are the same for ALL perfect and compound tenses (Perfect, Pluscuamperfect, Future Perfect, and Conditional Compound)! If you already learned them for the perfect tense, you already know them for conditional compound. Irregular past participles only have three possible endings: -to, -so, and -cho. The -soending is almost never used in everyday Spanish. The -cho ending appears in only two common verbs: dicho (from decir) and hecho (from hacer). Most irregular participles end in -to.
Here are the most important irregular past participles you need to know:
Note: Compound verbs follow the same pattern (e.g., descubrir → descubierto, devolver → devuelto, proponer → propuesto).
Past participles are the only form in Spanish grammar where both regular and irregular forms can coexist for the same verb! This means some verbs have two valid participle forms that are both correct.
Learning Tip: To make things easier, we recommend learning only the regular participle form (-ado/-ido) and just be aware that irregular forms exist. You'll understand both when you hear them, but you'll have fewer forms to memorize. Native speakers use both interchangeably, so you can't go wrong!
Just like with "would," we can also express "could have" and "should have" in Spanish. There are actually two ways to say each one!
poder (conditional) + haber + participle
Podría haber ayudado. - I could have helped.
¿Podrías haber venido? - Could you have come?
haber (conditional) + podido
Habría podido ayudar. - I could have helped.
¿Habrías podido venir? - Could you have come?
This form is very common in everyday Spanish!
deber (conditional) + haber + participle
Debería haber estudiado. - I should have studied.
Deberías haber dormido más. - You should have slept more.
haber (conditional) + debido
Habría debido estudiar. - I should have studied.
Habrías debido dormir más. - You should have slept more.
⚠️ This form is grammatically correct but NOT commonly used. Stick with "debería haber" for "should have."
Summary: For "could have," both podría haber and habría podidoare common (with "habría podido" being very popular). For "should have," use debería haber—it's the most natural choice. While "habría debido" exists, it's rarely used in everyday conversation.
