Déactiver – About the French Conditionnel Passé (Conditional Past) Tense

The French “Conditionnel Passé” is a compound tense used to express hypothetical or unreal actions in the past. It is formed by combining the conditional of the auxiliary verb “avoir” or “être” and the past participle of the main verb.

NOTE: To take a deep dive into all the French tenses then see my article on Mastering French Tense Conjugation.

Formation

Start with the conditional of the auxiliary verb: For most verbs, use “aurais” (for “avoir”) or “serais” (for “être”) as the conditional form. 

With “avoir”: j’aurais, tu aurais, il/elle/on aurait, nous aurions, vous auriez, ils/elles auraient. 
With “être”: je serais, tu serais, il/elle/on serait, nous serions, vous seriez, ils/elles seraient. 

Add the past participle of the main verb to this conditional form. 
For example, if you want to say “I would have done,” you would use “j’aurais fait.” If you want to say “She would have gone,” you would use “elle serait allée.”

Common Everyday Usage Patterns

Expressing Unreal Past Scenarios

The Conditionnel Passé is often used to talk about actions that did not happen in the past, but you are speculating about what would have occurred if they had. It’s a way to discuss hypothetical situations in the past. 

Si j’avais su, je t’aurais aidé. (If I had known, I would have helped you.)
Il serait venu s’il avait eu le temps. (He would have come if he had had the time.)

Interactions with Other Tenses

Conditional Present

You can use the Conditionnel Passé in combination with the conditional present to describe past actions that were hypothetical at the time they were spoken about. J’aurais aimé que tu m’appelles hier. (I would have liked you to call me yesterday.) 

Indicative Past Tenses

You might use the Conditionnel Passé alongside indicative past tenses like the passé composé to contrast hypothetical and real past events. Il est venu hier, mais s’il avait pu, il serait venu la semaine dernière. (He came yesterday, but if he could have, he would have come last week.) 

Conditional Future

In some cases, you can use the Conditionnel Passé in combination with the conditional future to discuss unreal past events that could have consequences in the future. Si j’avais réussi mon examen, j’aurais un meilleur travail. (If I had passed my exam, I would have a better job.)
