The past conditional (le conditionnel passé) is a compound tense used to state conditions in the past; it is formed with the auxiliary avoir meaning to have or être meaning to be, conjugated in the French present conditional , along with a past participle.
The conditional is a mood, and in the past tense it is used to express hypothetical statements, to say what would have happened or might have happened in the past. It is the equivalent of “would have,” “could have,” or “should have” + the past participle. For example:
In this post, we’ll cover how to form the past conditional in French, along with when to use it. Let’s get started!
How to form the past conditional in French?
To form the past conditional, you will follow the rules for compound tenses in French, using an auxiliary verb (avoir or être) and a past participle. You likely already know one of the most common French compound tenses: the passé composé. Like the passé composé, the past conditional in French follows many of the same compound tense rules.
Take a look at the passé composé and past conditional side by side. Can you see the difference?
| Passé composé |
|---|
j’ai compris meaning I understood |
elle est partie meaning she left |
nous sommes venus meaning we came |
elles sont sorties meaning they (fem.) went out |
| Past conditional |
|---|
j’aurais compris meaning I would have understood |
elle serait partie meaning she would have left |
nous serions venus meaning we would have come |
elles seraient sorties meaning they would have gone out |
Typically, only the conjugation of the auxiliary verb changes between compound tenses. To form the past conditional in French, the auxiliary verb is conjugated in the present conditional tense.

Here are the three steps to form the conditionnel passé meaning past conditional.
Step 1 - Choose if you are using the auxiliary avoir meaning to have or être meaning to be:
reflexive verbs in French, verbs of movement like aller meaning to go, venir meaning to come, or partir meaning to leave, and some verbs of change of state/condition, like devenir meaning to become, or partir meaning to leave, take the auxiliary être. All other verbs will use avoir. Learn the French verbs which require the auxiliary être and you'll be well on your way to conjugating the past conditional!
Step 2 - Conjugate the auxiliary in the French present conditional:
Avoir conjugation j’aurais meaning I would havetu aurais meaning you would haveil, elle, on aurait meaning he/she/we (inf.) would havenous aurions meaning we would havevous auriez meaning you would haveils, elles auraient meaning they would haveÊtre conjugation je serais meaning I would betu serais meaning you would beil, elle, on serait meaning he/she/we (inf.) would benous serions meaning we would bevous seriez meaning you would beils/elles seraient meaning they would beStep 3 - Add the past participle of the verb:
The past participle follows the same rules of agreement in French as in all compound tenses. Here is a recap of the main rules:
With être, the past participle agrees in number (singular/plural) and gender (masculine/feminine) with the subject.
Elle serait partie à 18h.Translation: She would have left at 6 pm.Les invités seraient montés au troisième étage.Translation: The guest would have gone up to the fourth story.Toutes les feuilles se seraient envolées avec le vent.Translation: All the leaves would have flown away with the wind.Generally, there is no agreement of the past participle with the auxiliary avoir, unless the direct object is placed before the verb.
direct objectPauline aurait acheté cette bague ancienne chez un antiquaire.Translation: Pauline would have bought this ancient ring from an antique dealer.La bague ancienne que Pauline aurait achetée chez un antiquaire vaut 600 €.Translation: The ancient ring that Pauline would have bought from an antique dealer is worth 600€.
Now that you know how to form the past conditional, let’s look at when you should use it.
When to use the past conditional in French?
Use the past conditional to express regrets, reproach, and imaginary scenarios in the past that can no longer happen, or to describe hypothetical situations using si meaning if. When you use the conditional in this tense, there is a sense of helplessness, regret, or relief, as there is nothing you can do to change what happened or didn't happen.
Let’s have a look at the uses in more detail.
With a hypothetical si meaning if construction in French, to mark a condition: if something had happened in the past, then another event could have occurred.

Let’s recap
When using the past conditional in French, keep the following tips in mind:
Use the past conditional when you want to say something “would have,” “could have,” or “should have” happened in the past.
Most of the time, you will use it with a si clause.
Conjugate the past conditional the same way you would construct the passé composé, except the auxiliary (être or avoir) must be conjugated in the present conditional.
The past participle agrees with the subject when you are using the auxiliary être.
There is no agreement of the past participle with the auxiliary avoir, except if the direct object is before the verb or using a direct object pronoun.
