What is the Subjunctive Mood in French?

The subjunctive is a verb mood used to express actions or ideas that are subjective or uncertain. Unlike the indicative, which states facts, the subjunctive is used for wishes, emotions, doubts, and, importantly, necessity. In French, recognizing when to use the subjunctive is key to sounding natural and sophisticated.

Why Use the Subjunctive to Express Necessity?

Necessity involves situations where something must happen or is required. In French, expressing necessity often signals a level of uncertainty or subjectivity, which is why the subjunctive is required. Phrases that introduce necessity usually trigger the use of the subjunctive mood in the dependent clause.

Common Expressions of Necessity Requiring the Subjunctive

Here are some of the most frequently used phrases to express necessity in French, all of which are followed by the subjunctive:

Each of these expressions sets up a situation where what follows is not a certain fact, but rather a necessity or obligation, thus requiring the subjunctive.

How to Form the Subjunctive in French

To use the subjunctive after expressions of necessity, you need to know how to conjugate verbs in the subjunctive. For most regular verbs, take the third person plural (ils/elles) form of the present indicative, drop the -ent ending, and add the subjunctive endings: -e, -es, -e, -ions, -iez, -ent.

For example, with the verb parler (to speak):

Remember, many common verbs are irregular in the subjunctive, so it’s important to learn those forms as well.

Examples: Expressing Necessity with the Subjunctive

Let’s look at how these necessity phrases work in real sentences:

Notice how each verb in the dependent clause (sois, fasse, comprenions, sachiez) is in the subjunctive.

Tips for Mastering the Subjunctive with Necessity

When Not to Use the Subjunctive for Necessity

If the subject in both clauses is the same, French often uses the infinitive rather than the subjunctive. For example:

Here, since the subject is implied to be the same (the person leaving), the infinitive partir is used instead of the subjunctive.

Conclusion

Expressing necessity is a fundamental skill in French, and mastering the subjunctive mood is essential to do so accurately. By learning the key phrases that require the subjunctive and practicing with real-life examples, you’ll be able to communicate with greater precision and fluency.
