Unconfirmed past events (le conditionnel passé)

The journalistic conditional

When reading the news or exploring historical mysteries in French, you will frequently encounter the conditionnel passé (past conditional). French uses this tense to report unconfirmed, alleged, or unverified past events.

It acts as a built-in "allegedly" or "reportedly." While it often translates literally to English as "would have," in this context it usually means "is said to have" or "supposedly did."

Apparently, the pharaoh would have caused the curse.
Apparemment, le pharaon aurait provoqué la malédiction.
The ancient city would have disappeared during a storm.
La cité antique aurait disparu pendant une tempête.

Forming the past conditional

To form the conditionnel passé, use the present conditional of the auxiliary verb (avoir or être) followed by the past participle of your main verb.

This structure is heavily used in archaeology and history to discuss rumors about uncovering or hiding ancient remains.

The researcher would have unearthed a king's skeleton.
Le chercheur aurait déterré le squelette d'un roi.
Apparently, the team would have buried the skeleton here.
Apparemment, l'équipe aurait enterré le squelette ici.

Investigating historical rumors

Whether you are talking about an expert deciphering a text or a mystery that supposedly remains unsolved, the past conditional distances you from the claim, showing that the information is not yet confirmed as fact.

The expert would have deciphered the old manuscript.
L'expert aurait déchiffré le vieux manuscrit.
Nobody would have deciphered this manuscript.
Personne n'aurait déchiffré ce manuscrit.
