The French subjunctive mood is used to express doubt, emotion, necessity, desire, possibility, and judgment. Students need this cheat sheet because the subjunctive often appears after common expressions with que. It helps learners recognize when the subjunctive is required and how to form it correctly.
A clear reference makes writing and speaking in more advanced French more accurate.
Key Facts
- The subjunctive is often used after expressions of will, wish, or command, such as vouloir que, souhaiter que, and demander que.
- The subjunctive is used after expressions of emotion, such as être content que, avoir peur que, and regretter que.
- The subjunctive is used after expressions of doubt or uncertainty, such as douter que, il est possible que, and il se peut que.
- To form the present subjunctive for many verbs, start with the ils/elles present tense stem, remove -ent, and add -e, -es, -e, -ions, -iez, -ent.
- For parler, the present subjunctive forms are que je parle, que tu parles, qu’il parle, que nous parlions, que vous parliez, qu’ils parlent.
- Some very common irregular subjunctive forms include être: que je sois, avoir: que j’aie, aller: que j’aille, and faire: que je fasse.
- Use the indicative after expressions of certainty or fact, such as je pense que, il est clair que, and il est vrai que when they are affirmative.
- The subjunctive usually appears in a dependent clause introduced by que, as in Il faut que tu étudies.
Vocabulary
- Subjunctive mood
- A verb mood used to express doubt, emotion, desire, necessity, or uncertainty rather than a simple fact.
- Indicative mood
- A verb mood used to state facts, describe reality, or express certainty.
- Trigger expression
- A phrase that signals the need for the subjunctive, such as il faut que or bien que.

- A part of a sentence that cannot stand alone and often begins with que in subjunctive sentences.
- Stem
- The base part of a verb used before adding endings to form a tense or mood.
- Irregular verb
- A verb that does not follow the normal conjugation pattern and must be memorized.
Common Mistakes to Avoid
- Using the indicative after il faut que is wrong because il faut que always expresses necessity and requires the subjunctive, as in Il faut que tu fasses tes devoirs.
- Forgetting the que clause is wrong because the subjunctive usually appears in a dependent clause, not as a stand-alone verb form.
- Using the infinitive when the subjects are different is wrong because French uses the subjunctive after que when each clause has its own subject, as in Je veux que tu viennes.
- Choosing the subjunctive after an affirmative fact expression is wrong because phrases like il est clair que and je sais que usually take the indicative.
- Applying regular endings to irregular verbs is wrong because verbs like être, avoir, aller, and faire have special subjunctive stems and forms.
Practice Questions
- 1 Conjugate the verb parler in the present subjunctive for nous in the sentence: Il faut que nous _____ français en classe.
- 2 Choose the correct form: Je veux que tu _____ avec moi. a) viens b) viennes c) venir
- 3 Complete the sentence with the correct mood: Il est certain que Marie _____ la réponse. Should the verb savoir be in the indicative or subjunctive?
- 4 Explain why Il faut que tu sois à l’heure uses the subjunctive instead of the indicative.
Understanding Subjunctive Mood Reference
A useful way to understand the subjunctive is to focus on the relationship between the two parts of a sentence. One person or idea reacts to, influences, or evaluates another action. In Il faut que tu étudies, the need comes from outside the action of studying.
The speaker does not present your studying as a settled fact. They present it as something required.
This pattern is common in school instructions, family rules, advice, news reports, and formal writing. French uses the mood to show the speaker's viewpoint toward the action, not just the time when it happens.
The subjects in the two clauses give an important clue. When the subject stays the same, French often uses an infinitive instead of que plus a subjunctive verb. Je veux partir means I want to leave.
The same person wants and leaves. Je veux que tu partes has two subjects, so the second verb takes the subjunctive. This distinction prevents many errors.
It is especially useful with verbs about wanting, preferring, fearing, and ordering. Students should first identify who performs each action before choosing a verb form.
Some expressions change meaning when they are negative or used as a question. Je pense qu'il vient normally treats his arrival as likely or factual, so it uses the indicative. Je ne pense pas qu'il vienne presents the arrival as uncertain, so French commonly uses the subjunctive.
The same shift can happen with croire and trouver. Context matters more than a fixed word list. Certain linking expressions nearly always call for the subjunctive because they introduce a condition, purpose, limit, or expectation.
Examples include pour que, bien que, avant que, and à moins que. Learn these as complete chunks, since the expression before que often determines the mood.
Verb formation needs careful attention because the singular forms and the ils form often sound alike. Que je parle, que tu parles, qu'il parle, and qu'ils parlent are pronounced almost the same in ordinary speech. The written endings still matter in assignments.
The nous and vous forms are often the best forms to check because they can reveal a different stem. For example, prendre gives que nous prenions, while venir gives que nous venions. A few verbs use two stems within the same subjunctive set.
Aller has j'aille but nous allions. Savoir has je sache but nous sachions. Memorize these high frequency verbs through short sentences rather than isolated tables.
When reading French, look for que, then find the verb before it. Decide whether that first expression states a fact, gives an opinion as certain, or shows a reaction, wish, doubt, necessity, or condition. Next, locate the subject of the second clause and check whether it differs from the first.
In writing, build the sentence in stages. Choose the main expression, add que, choose the correct subject, then form the verb. Reading your sentence aloud can help with rhythm, but it will not always reveal spelling errors.
Check the endings and irregular stems separately. With practice, the subjunctive becomes less like a special exception and more like a signal of how a speaker views an action.
