How many subjunctive forms do I actually need?

One. The présent du subjonctif covers essentially everything in speech and ordinary writing. The imparfait du subjonctif is literary and you will only ever need to recognise it, and the passé du subjonctif is a straightforward compound, que j’aie fait, que je sois allé, built from forms you already know.

Is there a shortcut for forming it?

For regular verbs, take the ils form of the present, drop -ent, and add -e, -es, -e, -ions, -iez, -ent. Ils finissent gives que je finisse. About ten verbs are irregular, être, avoir, aller, faire, pouvoir, savoir, vouloir, falloir, valoir, pleuvoir, and between them they account for most of what you will hear.

Do native speakers really use it?

Constantly, in the present tense. Il faut que, bien que and je veux que are everyday speech, not formal register. What has genuinely faded is the imperfect subjunctive, which now sounds archaic or comic outside literature. That is the form you can safely leave to reading.

Which one to useB2

Subjonctif vs indicatif

The short answer

The indicative states what is; the subjunctive appears when the sentence is not reporting a fact but reacting to one: wanting, doubting, fearing, judging. It is almost always set off by a specific expression followed by que, so the practical skill is recognising triggers rather than weighing moods.

How to choose

Ask these, in order

1
Is there a que, and what comes immediately before it?
The expression before que decides everything. If it is a fixed trigger, the mood is settled before you reach the verb.
Il faut que tu partes maintenant.
You need to leave now.
NBIl faut que is a trigger. Nothing about the second clause is under discussion.
2
Does the main clause state or ask about a fact?
Indicative. Knowing, saying, seeing, hoping and being certain all take the indicative.
Je sais qu’elle a raison.
I know she’s right.
3
Does it express will, need, doubt, emotion or a judgement?
Subjunctive. Vouloir que, il faut que, douter que, être content que, il est important que.
Je suis content que tu sois là.
I’m glad you’re here.
4
Is the subject the same on both sides of que?
Rewrite it with an infinitive instead. French avoids que when it does not need it.
Je veux partir tôt.
I want to leave early.
NBNot je veux que je parte. That is grammatical nonsense rather than a style choice.

Side by side

Each one, in full

Indicatif

When to use the indicative

States something as true.

The indicative is the default and covers everything the sentence puts forward as true. Verbs of knowing and saying take it: savoir, dire, voir, remarquer, expliquer, and so do the impersonal expressions of certainty: il est clair que, il est évident que, il paraît que.

Two of these surprise people. Espérer takes the indicative even though hoping is not certainty, and après que takes the indicative because the event it introduces has already happened. Both are worth learning as facts rather than reasoned about.

Il est évident qu’elle ne viendra pas.

It’s obvious she isn’t coming.

J’espère que tu vas mieux.

I hope you’re feeling better.

NBEspérer looks like a subjunctive trigger and is not. Souhaiter que, which means much the same, does take the subjunctive.

Je crois qu’il a compris.

I think he understood.

Subjonctif

When to use the subjunctive

Follows a trigger of will, doubt or emotion.

Four families of trigger cover almost everything you will need before C1: will and obligation (vouloir que, il faut que, exiger que), doubt and denial (douter que, ne pas croire que, il est possible que), emotion (être content, avoir peur, regretter que), and judgement (il est important, il vaut mieux, c’est dommage que).

A separate group is the conjunctions, which take the subjunctive purely by convention rather than because of any meaning you could reason out. Bien que, avant que, pour que, jusqu’à ce que, à moins que and sans que are the ones that carry the traffic.

Bien qu’il fasse froid, on sort.

Even though it’s cold, we’re going out.

NBBien que always takes the subjunctive, however factual the cold is.

Il vaut mieux que vous preniez le train.

You’d be better off taking the train.

Je doute qu’elle puisse venir.

I doubt she can come.

Mistakes to avoid

What learners actually get wrong

J’espère que tu viennes.
J’espère que tu viendras.
Espérer takes the indicative, which is the single most common subjunctive error. Souhaiter que, a near synonym, takes the subjunctive, so the meaning cannot be used as a guide here; only the verb can.
Je pense qu’il soit malade.
Je pense qu’il est malade.
Penser and croire take the indicative in the affirmative. They flip to the subjunctive only when negated or questioned: je ne pense pas qu’il soit malade, penses-tu qu’il soit malade ?
Je veux que je parte.
Je veux partir.
When both halves have the same subject, French drops que and uses an infinitive. Keeping que is not merely clumsy. It is not a possible French sentence.
Après qu’il soit parti, nous avons dîné.
Après qu’il est parti, nous avons dîné.
Après que takes the indicative, because what it introduces has actually happened. Avant que takes the subjunctive. Native speakers get this one wrong often enough that you will see both, but only one is correct.

Subjonctif présent

Spot the trigger, then pick subjonctif or indicatif. Reading a rule and being able to apply it are different skills, and only one of them shows up when you speak.
