Value of the past conditional
The past conditional places an action in the past, but without presenting it as a realized fact. It is used for an imagined action, possible at another time, or prevented by another situation. The pattern is often: si + past conditional, + past conditional. In Il serait venu s’il avait eu le temps, the coming is imagined in the past, but it did not occur.
Regret and reproach
After the fact, the past conditional serves to say what could have happened but did not. With J’aurais dû l’appeler, the speaker expresses regret. With Tu aurais pu prévenir, they express a reproach. The form distances the action and shows that it belongs to the realm of the unaccomplished. For the formation, the auxiliary comes from the Conditionnel, then the meaning is completed by the Participe Passé.
| Usage | Explanation | |
|---|---|---|
| On emploie le conditionnel passé pour dire qu’on aurait voulu agir autrement dans le passé. | ||

Auxiliary avoir in the conditional
With most verbs, the past conditional is built with avoir in the present conditional + past participle. We thus obtain j’aurais mangé, tu aurais fini, il aurait vendu, nous aurions parlé, vous auriez choisi, ils auraient pris. Each form first contains the auxiliary in the conditional, then the past participle of the main verb.

Auxiliary être in the conditional
Some verbs take être in the present conditional + past participle: je serais allé, tu serais parti, elle serait montée, nous serions venus, vous seriez sortis, elles seraient restées. These verbs often mark movement or a change of state. With être, the past participle agrees with the subject in gender and number, as in Accord du passé.

|---|---|---|
| tu | être | |
| je | être | |

Regular past participles
Many verbs keep a regular past participle. Verbs ending in -er most often give -é: parler + parlé, aimer + aimé. Verbs ending in -ir often take -i: finir + fini, choisir + choisi. Verbs ending in -re often give -u: vendre + vendu, attendre + attendu. The past conditional thus combines the auxiliary in the conditional with this regular past participle.
| Subject | Infinitive | Conjugation |
|---|---|---|
| parler | parler | |
| rendre | rendre | |
| finir | finir |
| Subject | Infinitive | Conjugation | |

Irregular past participles
Some common verbs do not follow regular forms and require a past participle to be learned by heart. We find avoir → eu, être → été, faire → fait, dire → dit, prendre → pris, mettre → mis, voir → vu, pouvoir → pu, vouloir → voulu, lire → lu, écrire → écrit. In the past conditional, these forms appear after the auxiliary: j’aurais eu, il aurait fait, nous serions partis.

Agreement with être
When the past conditional is built with être, the past participle agrees with the subject. We write il serait allé in masculine singular, elle serait allée in feminine singular, ils seraient allés in masculine plural, elles seraient allées in feminine plural. The agreement is on the past participle, not on the auxiliary. With avoir, there is no such agreement with the subject in the simplest form.

Softening information
In everyday language, the past conditional allows reporting information without asserting it directly. It is used in sentences like The accident would have been caused by a tired driver or The minister would have submitted his resignation. The form indicates that the information is reported with caution, often from an indirect source. The sentence maintains a less direct tone than the passé composé.
| Usage | Explanation | |
|---|---|---|
| On l’utilise pour rapporter une information sans l’affirmer totalement. | ||
| Il sert à garder une petite distance avec ce qu’on annonce. | ||
| On l’emploie aussi pour parler d’une hypothèse sur un fait passé. |

Choosing passé composé or conditional
The passé composé presents a fact as real and accomplished: He left at ten o’clock. The past conditional presents a fact not realized, imagined, or supposed: He would have left at ten o’clock or He would have left earlier if he could have. In a sentence with si and a past condition, the passé composé describes the realized condition and the past conditional describes the absent result. If the action is told as certain, one chooses the passé composé; if it is thought, regretted, or reported with distance, one chooses the past conditional.

Common spoken forms
In speech, contractions of the auxiliary quickly bind to the subject: j’aurais, t’aurais, y aurait, j’aurais eu. The past conditional remains recognizable because the first part carries the conditional mark and the second part remains the past participle. In spontaneous speech, the sound chain may be shorter, but the structure always remains: auxiliary in the conditional + past participle.
