If you've been studying French for more than a few months, someone has probably told you the subjunctive is "the mood of doubt and emotion." That's true. It's also useless when you're actually trying to form a sentence in real time.

Here's the truth nobody says out loud: native French speakers don't think about the subjunctive. They hear a trigger word and the right form pops out. That's all this article is, the trigger list, and the one rule for forming the conjugation.

The one rule for forming the subjonctif présent

For regular verbs, the recipe is:

  1. Take the 3rd person plural (ils / elles) form of the présent indicatif.
  2. Drop the -ent ending.
  3. Add the subjunctive endings: -e, -es, -e, -ions, -iez, -ent.

Example with parler (to speak):

  • ils parlent → stem parl-
  • que je parle, que tu parles, qu'il parle, que nous parlions, que vous parliez, qu'ils parlent

Notice nous and vous look like the imparfait (parlions / parliez). For regular verbs, the stems match.

Watch for two stems. With verbs such as prendre and venir, use the present ils stem for je, tu, il/elle, and ils/elles, but the present nous stem for nous and vous:

  • ils prennent → que je prenne, but nous prenons → que nous prenions, que vous preniez.
  • ils viennent → que je vienne, but nous venons → que nous venions, que vous veniez.

⚠️ Learn the common irregular forms separately: être, avoir, aller, faire, pouvoir, vouloir, savoir, valoir, falloir, and pleuvoir.

Common expressions, not a complete trigger algorithm

The subjunctive shows up in a subordinate clause introduced by que, after a trigger in the main clause. Memorize the triggers, not the meaning.

1. Impersonal expressions of necessity, possibility, doubt

Trigger What it means
Il faut que It's necessary that…
Il est nécessaire que It's necessary that…
Il est important que It's important that…
Il est possible que It's possible that…
Il est impossible que It's impossible that…
Il vaut mieux que It's better that…
Il est temps que It's time that…
Il se peut que It might be that…

Il faut que tu fasses tes devoirs. You have to do your homework. (faire → subjonctif) Il vaut mieux qu'on parte maintenant. Better that we leave now. (partir → subjonctif)

2. Verbs of wanting, wishing, ordering, forbidding

Trigger What it means
vouloir que to want that
souhaiter que to wish that
désirer que to desire that
exiger que to demand that
préférer que to prefer that
ordonner que to order that
interdire que to forbid that
permettre que to allow that

Je veux que tu viennes. I want you to come. (venir → subjonctif) Elle préfère que nous soyons à l'heure. She prefers that we be on time. (être → subjonctif)

For wishes such as vouloir, a shared subject normally uses an infinitive: je veux venir, compared with je veux que tu viennes. This is not a universal ban on the same subject in every subjunctive construction. Also, que alone does not select the subjunctive: je sais qu'il vient uses indicative.

3. Verbs and expressions of emotion

Trigger What it means
être content / heureux que to be happy that
être triste que to be sad that
être désolé que to be sorry that
être surpris / étonné que to be surprised that
avoir peur que to be afraid that
regretter que to regret that
C'est dommage que It's a shame that

Je suis content que tu sois là. I'm glad you're here. J'ai peur qu'il ne vienne pas. I'm afraid he won't come.

4. Verbs of doubt and denial

Trigger What it means
douter que to doubt that
ne pas croire que not to believe that
ne pas penser que not to think that
ne pas être sûr que not to be sure that
Il est douteux que It's doubtful that

Je doute qu'il sache la réponse. I doubt he knows the answer. Je ne pense pas qu'elle vienne. I don't think she'll come.

Compare the common patterns je pense qu'il vient and je ne pense pas qu'il vienne. Negation and questions can involve choices of commitment or meaning, so this contrast is not a rule that every negative phrase has exactly one possible mood.

5. Subjunctive conjunctions

These conjunctions always trigger the subjunctive, no exceptions:

Conjunction English
bien que although
quoique even though
avant que before
jusqu'à ce que until
pour que / afin que so that
à condition que provided that
à moins que unless
sans que without
de peur que / de crainte que for fear that
pourvu que as long as

Bien qu'il fasse froid, nous sortons. Although it's cold, we're going out. Je te prête mon livre pour que tu le lises. I'll lend you my book so you can read it.

The mental model

Free practice · 10 questions

Indicative or subjunctive? Test the trigger

Choose the mood for the missing verb, not its conjugated form. Each answer explains the trigger and shows the completed sentence.

Practice only, not a placement test. The questions and answer key remain available below.

Practice questions and answer key
  1. Necessity: il faut que

    Il faut que tu ___ tes devoirs. (faire)

    Il faut que tu fasses tes devoirs.

    Il faut que expresses necessity, so the subordinate verb takes the subjunctive: fasses.

  2. Certainty: je sais que

    Je sais qu'il ___ ce soir. (venir)

    Je sais qu'il vient ce soir.

    Je sais que presents the information as known. Que alone does not trigger the subjunctive: vient is indicative.

  3. A wish with a different subject

    Je veux que nous ___ ensemble. (partir)

    Je veux que nous partions ensemble.

    Vouloir que expresses a wish. The main subject is je and the subordinate subject is nous, so use the subjunctive.

  4. An affirmative belief

    Je pense qu'elle ___ raison. (avoir)

    Je pense qu'elle a raison.

    Here the speaker asserts a belief, rather than expressing doubt. Affirmative je pense que normally takes the indicative.

  5. A negative belief expressing doubt

    Je ne pense pas qu'elle ___ raison. (avoir)

    Je ne pense pas qu'elle ait raison.

    Negating penser expresses doubt in this sentence, so use ait. Compare the indicative a in the previous question.

  6. Concession: bien que

    Bien qu'il ___ fatigué, il continue. (être)

    Bien qu'il soit fatigué, il continue.

    Bien que takes the subjunctive, even when the speaker accepts the fact as true. The mood is not just about uncertainty.

  7. An explicit statement of certainty

    Il est certain qu'ils ___ réussir. (pouvoir)

    Il est certain qu'ils peuvent réussir.

    Il est certain que states certainty and takes the indicative. Do not confuse it with il est possible que.

  8. Purpose: pour que

    Je te donne ce livre pour que tu le ___. (lire)

    Je te donne ce livre pour que tu le lises.

    Pour que introduces a purpose and takes the subjunctive. The intended reading is not being stated as an established fact.

  9. A cause presented as a fact

    Parce qu'il ___ fatigué, il se repose. (être)

    Parce qu'il est fatigué, il se repose.

    Parce que introduces a factual cause here. It contains que, but it does not require the subjunctive.

  10. Before an event: avant que

    Avant que nous ___ une décision, nous discutons. (prendre)

    Avant que nous prenions une décision, nous discutons.

    Avant que takes the subjunctive. For nous, prendre uses pren- from nous prenons, not prenn- from ils prennent.

Use the diagnostic above to separate a trigger that requires the subjunctive from a phrase that happens to contain que. If you miss the mood, reread the relevant trigger category. If you choose the mood correctly but cannot produce the form, practise its endings in the French conjugation memory drill.

When you're producing French in real time, you don't think "hmm, this expresses doubt, so subjunctive." You hear yourself say one of the triggers above, and the subjunctive form follows automatically, because your brain has been wired to associate il faut que with the subjunctive shape.

That wiring takes reps. Reading this article won't get you there. You need to produce the conjugation hundreds of times, each time triggered by one of these phrases, until the link between trigger and form is unconscious.

This page covers when to use the mood. For endings, stem formation, and irregular forms, see the French subjunctive conjugation guide.

That's exactly what we built Bonjour Verbs for. The subjunctive milestone takes you through every trigger category above, with typed-answer practice on real sentence frames, "Il faut que tu ____ (faire) tes devoirs", and stepwise feedback when you miss. By the time you graduate the milestone, the triggers fire automatically.
