French Subjunctive Explained: Complete Guide with Examples
Introduction: What Is the French Subjunctive?
The French subjunctive (le subjonctif) is a grammatical mood used to express doubt, desire, emotion, necessity, and uncertainty. Unlike the indicative mood, which states facts, the subjunctive conveys subjective attitudes toward actions or states. Understanding the French subjunctive explained in practical terms is essential for achieving fluency, as it appears frequently in everyday speech and writing.
The subjunctive typically appears in subordinate clauses introduced by que (that), following specific triggers in the main clause. When you learn French subjunctive, you'll discover it's not as difficult as its reputation suggests—most verbs follow predictable patterns.
Formation: French Subjunctive Conjugation
To master French subjunctive conjugation, you need to understand how regular and irregular verbs form this mood. For most verbs, the subjunctive stem comes from the third person plural (ils/elles) form of the present indicative, with the -ent ending removed.

| que je | parle |
| que tu | parles |
| qu'il/elle/on | parle |

Common Mistakes
When learning how to use subjunctive in French, learners often make these errors:
1. Using Subjunctive After "espérer que"
Unlike other verbs of desire, espérer (to hope) takes the indicative, not the subjunctive:
- Incorrect: J'espère qu'il vienne.
- Correct: J'espère qu'il viendra. (I hope he will come.)
2. Forgetting the Subjunctive After "bien que"
Many learners use the indicative after bien que (although), but it always requires the subjunctive:
- Incorrect: Bien qu'il est malade...
- Correct: Bien qu'il soit malade... (Although he is sick...)
3. Using Subjunctive When Subjects Are the Same
When the subject of both clauses is the same, use an infinitive instead of the subjunctive:
- Incorrect: Je veux que je parte.
- Correct: Je veux partir. (I want to leave.)
4. Confusing "penser que" and "ne pas penser que"
Affirmative penser que takes the indicative, but negative ne pas penser que takes the subjunctive:
- Je pense qu'il a raison. (indicative) — I think he is right.
- Je ne pense pas qu'il ait raison. (subjunctive) — I don't think he is right.
5. Incorrect Irregular Verb Forms
Memorize the irregular subjunctive forms carefully. Common errors include:
- Using *est instead of soit for être
- Using *a instead of ait for avoir
- Using *va instead of aille for aller
6. Overusing the Subjunctive
Not every que clause requires the subjunctive. Expressions of certainty and declaration use the indicative:
- Je sais qu'elle est là. (indicative) — I know she is there.
- Il est certain qu'il viendra. (indicative) — It is certain he will come.
