O que você vai aprender

Hey friend! Ready to take a huge step forward in your French journey? This chapter is where you'll really feel your language skills become super practical. Don't worry, even if subjunctive sounds a bit intimidating, I promise it's much easier than you think here! In this chapter, you'll learn exactly how to say

something must be done,
"it's important that X happens, and even I want you to do Y" in French. Specifically, you'll master: * **il faut que + subjunctive:** To express general necessity or to tell someone what *they* specifically must do. Imagine you're in France and need to remind a friend:
We *must* buy the tickets!
(il faut qu'on achète les billets!). * **il est nécessaire que + subjunctive:** For when you need to state a requirement more formally or emphatically, like in a professional setting: "It's *necessary* that we submit the report by tomorrow." (il est nécessaire qu'on rende le rapport demain.). * **il est important que + subjunctive:** To politely yet firmly emphasize priorities, such as when you want to say, "It's *important* that everyone arrives on time." (il est important que tout le monde arrive à l'heure.). * And generally, how to use the subjunctive after que to express your desires, wishes, or demands. All these structures help you convey your meaning with greater precision, and they share a common thread: the main verb after que will be in the subjunctive mood. It might seem a little unusual at first, but don't worry, with just a bit of practice, you'll get the hang of it! By the end of this chapter, you'll confidently be able to articulate what needs to happen, what's crucial to you, and what you want from others in French. You'll speak much more decisively and clearly. Ready? Let's go!

How This Grammar Works

In this chapter, we're diving deep into how to express necessity, obligation, and importance in French, primarily using expressions that trigger the subjunctive mood. This is key for B1 French speakers looking to communicate more effectively.
First up, we have il faut que + subjunctive. This structure, covered in "French Necessity: Using 'il faut que' + Subjunctive and French Necessity: Must & Have To (il faut que)
, is incredibly versatile. It can express a general necessity, like
one must or it is necessary," or it can tell a specific person what they must do.
For example, if you need to remind a friend: Il faut qu'on achète les billets ! (We must buy the tickets!). Or, Il faut que tu fasses tes devoirs. (You must do your homework.). Notice how the verb after que (acheter, faire) is in the subjunctive.
Next, for a slightly more formal or emphatic tone, we use il est nécessaire que + subjunctive. This aligns with the "French Necessity: It's Necessary That..." rule. It's perfect for professional settings or when stating a firm requirement.
For instance: Il est nécessaire qu'on rende le rapport demain. (It's necessary that we submit the report tomorrow.).
Then, to politely yet firmly emphasize priorities, we use il est important que + subjunctive. This is detailed in
French Subjunctive: It is Important that...
and "It's Important That... (Subjunctive after 'il est important que')".
This structure is great for expressing what matters to you or for setting expectations. For example: Il est important que tout le monde arrive à l'heure. (It's important that everyone arrives on time.).
All these expressions fall under the umbrella of
French Subjunctive: Expressing Wants and Will (Subjonctif de volonté)
. They convey a desire, an obligation, or a judgment from the speaker, hence the need for the subjunctive mood. To form the present subjunctive, generally, you take the *ils* form of the present indicative, remove the -ent ending, and add the subjunctive endings: -e, -es, -e, -ions, -iez, -ent.
Of course, there are irregular verbs, but the context will often guide you!

Common Mistakes

  1. 1✗ Wrong: *Il faut que tu vas au supermarché.*
✓ Correct: *Il faut que tu ailles au supermarché.* (You must go to the supermarket.)
*Explanation:* After expressions like il faut que, il est nécessaire que, and il est important que, the verb in the dependent clause *always* requires the subjunctive mood, not the indicative. Vas is indicative, ailles is subjunctive.
  1. 1✗ Wrong: *Il est important que nous parlons clairement.*
✓ Correct: *Il est important que nous parlions clairement.* (It is important that we speak clearly.)
*Explanation:* Even if the indicative and subjunctive forms look similar for some verbs (like *parler* in the *nous* form), it's crucial to use the correct subjunctive conjugation. For regular -er verbs, the *nous* and *vous* subjunctive endings are -ions and -iez, not -ons and -ez.
  1. 1✗ Wrong: *Il faut que prendre le train.*
✓ Correct: *Il faut prendre le train.* (One must take the train.) OR *Il faut que nous prenions le train.* (We must take the train.)
*Explanation:* Il faut + infinitive is used for a general, impersonal necessity (no specific subject). Il faut que + subjunctive is used when there's a specific subject performing the action after que. Don't mix them up!

Quick FAQ

Q

When do I use il faut vs. il faut que?

Use il faut + infinitive for general, impersonal necessities (e.g., *Il faut manger pour vivre.* - One must eat to live). Use il faut que + subjunctive when there's a specific subject performing the action (e.g., *Il faut que tu manges.* - You must eat.).

Q

Is the subjunctive always used after que?

No, not always! The subjunctive is used after que only when the main clause expresses a doubt, a wish, a necessity, an emotion, or a judgment. If the main clause states a fact or certainty, the indicative mood is used after que.

Q

How do I know the subjunctive form of a verb?

For most regular verbs, take the *ils* form of the present indicative, remove the -ent ending, and add the subjunctive endings: -e, -es, -e, -ions, -iez, -ent. Many common verbs are irregular, so memorization and practice are key!

Q

Can I use these expressions to talk about past events?

While these structures primarily trigger the present subjunctive for actions happening now or in the future, it is possible to use the *passé du subjonctif* (past subjunctive) for actions that happened in the past. However, this is a more advanced topic for B2+ learners and less common in everyday speech.

Cultural Context

These structures are incredibly common in everyday French conversation, reflecting a society that often values clear communication of expectations and desires. Il faut que is ubiquitous and can range from a gentle suggestion to a firm demand depending on tone. Il est nécessaire que adds a layer of formality or official requirement, often heard in professional or administrative contexts.
Il est important que allows for emphasizing priorities while maintaining a polite, persuasive tone. Mastering these phrases will make your French sound much more natural and allow you to navigate social and professional situations with greater confidence. There are no significant regional differences in the usage of these core grammatical patterns across French-speaking areas.

Erros comuns

Many learners accidentally use the indicative (present tense) after 'que'. 'Faire' is irregular in the subjunctive; 'fasses' is required.

Wrong: Il faut que tu fais tes devoirs.
Correto: Il faut que tu fasses (subjunctive) tes devoirs.

In English, we say 'I want you to go' (Infinitive). In French, you MUST use 'que' followed by a new clause with a conjugated verb in the subjunctive.

Wrong: Je veux partir que tu.
Correto: Je veux que tu partes.

For -er verbs, the 'nous' and 'vous' forms of the subjunctive look like the 'imparfait'. Don't forget that extra 'i'!

Wrong: Il est important que nous parlons.
Correto: Il est important que nous parlions (subjunctive).

Next Steps

You've just tackled one of the most famous parts of French grammar. The subjunctive might seem scary, but you're handling it like a pro! Keep practicing these 'que' triggers.

Perguntas comuns (4)

Significa 'é necessário que' ou 'alguém deve'. É usado para expressar obrigação ou necessidade para uma pessoa específica. Pense em 'Você deve estudar', que em francês seria
Il faut que tu étudies
.
Você pode usar 'devoir' (dever), mas 'il faut que' é muito mais comum no francês falado e soa mais natural. É uma parte fundamental para soar como um nativo. Por exemplo,
Il faut que tu partes
soa mais natural que 'Tu dois partir' em muitos contextos.
O francês não funciona como o português ou inglês aqui. Você precisa usar a 'ponte' 'que' e depois uma oração completa com um verbo no subjuntivo. Por exemplo, 'Je veux que tu partes'.
Sim, quando você o usa como 'J'aimerais que...' (Eu gostaria que...), ele quase sempre ativa o subjuntivo porque você está expressando um desejo. Tipo em 'J'aimerais que tu viennes'.
