Conjugation

When to Use the Subjunctive

The formation of the present subjunctive was presented in subjonctif présent derivation. The present lesson introduces the first major category of triggers: impersonal expressions that convey necessity, obligation, or importance. These structures require the subjunctive in the subordinate clause.

Necessity Triggers + Subjunctive

Trigger	Meaning	Example
il faut que	it is necessary that	Il faut que vous arriviez à l’heure.
il est nécessaire que	it is necessary that	Il est nécessaire que chacun fasse des efforts.
il est important que	it is important that	Il est important que tu comprennes les règles.
il est essentiel que	it is essential that	Il est essentiel que nous protégions l’environnement.
il est obligatoire que	it is compulsory that	Il est obligatoire que les salariés portent un badge.
il est indispensable que	it is indispensable that	Il est indispensable que vous lisiez le règlement.

Structure

All the expressions listed above follow the same pattern: trigger + que + subject + subjunctive verb.
- Il faut que je finisse le rapport.
- Il est essentiel que nous prenions une décision.

When there is no change of subject, the infinitive is used after the impersonal expression, without que: Il faut finir le rapport.

Negative and Interrogative Forms

The subjunctive remains in the subordinate clause even when the main clause is negated or interrogative:
- Il n’est pas nécessaire que tu viennes.
- Est‑il indispensable que nous signions le contrat ?

Examples

Il faut que nous réduisions les déchets dans l'entreprise.
The subjunctive form réduisions is triggered by Il faut que.
Il est important que chaque employé respecte le règlement intérieur.
The verb respecte is in the subjunctive after Il est important que.
