The subjunctive mood — le subjonctif — is one of the most important and distinctive features of French grammar. For English speakers, it can seem mysterious at first, but once you understand its logic, it becomes an essential tool for expressing the full range of human thought and feeling in French.
Before diving into the subjunctive itself, let's clarify what a mood (un mode) is. In French grammar, a mood is a way of expressing the speaker's attitude toward the action described by the verb. French has several moods:
| Mood | French Name | Purpose | Example |
|---|---|---|---|
| Indicative | l'indicatif | States facts, describes reality | Elle parle français. (She speaks French.) |
| Subjunctive | le subjonctif | Expresses wishes, doubts, emotions, necessity | Je veux qu'elle parle français. (I want her to speak French.) |
| Conditional | le conditionnel | Expresses hypotheticals, politeness | Elle parlerait français. (She would speak French.) |
| Imperative | l'impératif | Gives direct commands | Parle français ! (Speak French!) |
A tense (un temps) tells you when something happens — present, past, or future. A mood tells you how the speaker views the action — as a fact, a wish, a doubt, or a command.
Key insight: The subjunctive is not about time. It is about the speaker's perspective on reality.
The indicative is the "default" mood. You use it for:
The subjunctive appears when the speaker is not stating a simple fact. It is triggered by:
The core principle: The indicative presents actions as real and certain. The subjunctive presents actions as desired, doubted, felt about, or judged — in other words, filtered through the speaker's subjectivity.
English does have a subjunctive, but it has largely faded from everyday use. Most English speakers use it without realising:
| English Subjunctive | Explanation |
|---|---|
| If I were you... | Not "was" — this is subjunctive |
| I suggest that he be on time. | Not "is" — this is subjunctive |
| God save the King. | Not "saves" — this is subjunctive |
| It's important that she arrive early. | Not "arrives" — this is subjunctive |
| I wish I were taller. | Not "was" — this is subjunctive |
In English, the subjunctive is often replaced by modal verbs ("should," "would") or simply ignored. But in French, the subjunctive is mandatory. You cannot skip it or replace it with another construction. Using the indicative where the subjunctive is required will make your French sound incorrect and unnatural.
The subjunctive almost always appears in a subordinate clause introduced by que (that). The main clause contains the "trigger" — a verb or expression that calls for the subjunctive:
[Main clause with trigger] + que + [subordinate clause in subjunctive]
Examples:
| Main Clause (Trigger) | que | Subordinate Clause (Subjunctive) |
|---|---|---|
| Je veux (I want) | que | tu viennes. (you come.) |
| Il faut (It is necessary) | que | nous partions. (we leave.) |
| Je doute (I doubt) | que | il sache. (he knows.) |
| Elle est triste (She is sad) | que | tu partes. (you are leaving.) |
French subjunctive triggers can be organised into these major categories:
When you express what you want, prefer, or wish someone else to do:
When you react emotionally to a situation:
When you express doubt or uncertainty about something:
When you express that something must happen:
When you make a value judgment about a situation:
Like in other Romance languages, the subjunctive typically requires two different subjects:
| Structure | Construction | Why |
|---|---|---|
| Je veux partir. (I want to leave.) | Infinitive | Same subject (je...je) |
| Je veux que tu partes. (I want you to leave.) | Subjunctive | Different subjects (je...tu) |
| Elle préfère rester. (She prefers to stay.) | Infinitive | Same subject (elle...elle) |
| Elle préfère que nous restions. (She prefers that we stay.) | Subjunctive | Different subjects (elle...nous) |
Rule: When the subject is the same in both clauses, French uses the infinitive. When the subjects are different, French uses que + subjunctive.
Not every expression with que triggers the subjunctive. Some expressions state facts or certainty, which means they take the indicative:
| Indicative (certainty/fact) | Subjunctive (wish/doubt/emotion) |
|---|---|
| Je sais que tu as raison. | Je doute que tu aies raison. |
| Il est certain qu'il vient. | Il est possible qu'il vienne. |
| Je crois qu'elle est là. | Je ne crois pas qu'elle soit là. |
| Je pense qu'il fait beau. | Je ne pense pas qu'il fasse beau. |
| Il est vrai qu'il pleut. | Il faut qu'il pleuve pour les plantes. |
Notice: Croire and penser in the affirmative take the indicative (they express belief/certainty). In the negative, they take the subjunctive (negation introduces doubt).
In the following lessons, we will learn:
By the end of this course, you will be able to identify subjunctive triggers, conjugate verbs correctly, and use complex French structures with confidence.
The subjunctive (le subjonctif) is a mood — not a tense — that expresses subjectivity: wishes, emotions, doubt, necessity, and judgment. English barely uses it, but French relies on it constantly. The subjunctive almost always appears after que in a subordinate clause, and it typically requires two different subjects (otherwise, use the infinitive). Understanding the subjunctive unlocks an essential dimension of French expression, from simple daily conversation to sophisticated written French.
