Déraisonner – About the French Subjonctif Passé (Subjunctive Past) Tense

The French Subjonctif Passé is a verb tense used to express actions or states that are uncertain, hypothetical, or dependent on some condition in the past. It’s often used in conjunction with the main verb in the present or future tense to convey various nuances of doubt, desire, necessity, or emotion.

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

Formation of the Subjonctif Passé

To form the Subjonctif Passé, you generally need to start with the third person plural (ils/elles) form of the passé composé (a compound past tense). Then, drop the subject and replace it with the appropriate Subjonctif endings. The endings are the same for regular -er, -ir, and -re verbs:

   – For -er verbs: -e, -es, -e, -ions, -iez, -ent
   – For -ir verbs: -isse, -isses, -ît, -issions, -issiez, -issent
   – For -re verbs: -e, -es, -e, -ions, -iez, -ent

For example, if you have the verb “parler” (to speak) in the third person plural passé composé, which is “ils ont parlé” (they spoke), the Subjonctif Passé form would be “qu’ils aient parlé” (that they spoke).

Everyday Usage Patterns

The Subjonctif Passé is commonly used in various situations:

– Expressing doubt or uncertainty: It’s used when you’re not certain about the completion of an action in the past. For example, “Je doute qu’il ait mangé” (I doubt that he ate).

– Desires and preferences: When you want or wish for something to have happened in the past. For instance, “Je préfère que tu aies réussi” (I prefer that you have succeeded).

– Expressing emotions: To convey emotions or feelings related to past actions or events. For example, “Il est content que nous ayons gagné” (He is happy that we won).

– Hypothetical situations: When discussing hypothetical or unreal past situations. For example, “Si j’avais su, j’aurais souhaité qu’ils aient été là” (If I had known, I would have wished they had been there).

Interactions with Other Tenses

The Subjonctif Passé often interacts with other tenses to convey specific meanings:

Present tense

It’s commonly used after expressions of doubt, desire, necessity, or emotion in the present. For example, “Il faut que tu aies fini” (You must have finished).

Future tense

It’s used in the future for hypothetical or unreal actions in the past when the main clause is in the future. For example, “Je douterai qu’ils aient terminé demain” (I will doubt that they have finished tomorrow).

Conditional

When the main clause is in the conditional, the Subjonctif Passé can be used to express unreal or hypothetical actions in the past. For instance, “Il voudrait que nous ayons réussi” (He would like us to have succeeded).

Summary

The Subjonctif Passé is a versatile tense used in French to convey uncertainty, doubt, desire, or hypothetical situations related to past actions. It is used in various everyday contexts and interacts with other tenses to express specific nuances in the language.
