Does je pense que take the subjunctive?

Not when it is affirmative. Je pense qu'il vient uses the indicative, because you are putting the statement forward as true. The subjunctive appears once you negate or question it: je ne pense pas qu'il vienne.

Which French verbs change mood when negated?

Penser, croire, trouver, dire, espérer, être sûr, être certain, être évident, il est vrai, and il me semble. All take the indicative when affirmative and admit the subjunctive when negative or interrogative.

Is the subjunctive compulsory after je ne pense pas que?

Not strictly. Careful and written French uses it, but spoken French often keeps the indicative, and keeping it hints that you privately believe the clause anyway. Both versions are understood without difficulty.

Why does espérer take the indicative when vouloir takes the subjunctive?

Because espérer treats the outcome as something expected rather than willed. J'espère qu'il viendra looks forward to a likely event, while je veux qu'il vienne imposes a wish, and only imposition triggers the subjunctive in French.

What is the difference between il semble que and il me semble que?

The pronoun. Il me semble que anchors the impression in a person and takes the indicative: il me semble qu'elle a raison. Il semble que is impersonal and takes the subjunctive: il semble qu'elle ait raison.

The Variable Subjunctive: When Penser, Croire and Être Sûr Change Mood

Written by Camille Laurent, Lead French Curriculum Editor · Reviewed May 2026

A small group of French verbs takes the indicative when you assert something and the subjunctive when you deny it or ask about it. Je pense qu'il vient states a belief, while je ne pense pas qu'il vienne withdraws it, and the mood moves with the certainty.

Je ne pense pas qu'il vienne ce soir.

I don't think he's coming tonight.

What it is

Most subjunctive triggers are fixed: il faut que always takes it, savoir que never does. A handful of verbs sit in between. They express a judgement, and as long as you are making that judgement the clause is presented as true and takes the indicative. Take the judgement away by negating it or turning it into a question, and the clause loses its guarantee, which is exactly what the subjunctive marks.

Je crois qu'elle a raison, mais je ne crois pas qu'elle ait tort. — I think she's right, but I don't think she's wrong.

How to spot it

Check whether the main verb is affirmative. Affirmative penser, croire, trouver, espérer and être sûr all take the indicative. Put ne … pas around them or invert them into a question and the subjunctive becomes available.

Je pense qu'il a compris. — I think he understood. (indicative)
Je ne pense pas qu'il ait compris. — I don't think he understood. (subjunctive)
Penses-tu qu'il ait compris ? — Do you think he understood ?
Es-tu sûr que ce soit la bonne adresse ? — Are you sure this is the right address ?

The subjunctive here is available rather than compulsory. Spoken French frequently keeps the indicative after a negated penser, and nobody treats it as wrong.

Common Variable Subjunctive Examples in French

Each verb in both of its states:

Penser and Croire

Je pense que c'est une bonne idée.: I think it's a good idea.
Je ne pense pas que ce soit une bonne idée.: I don't think it's a good idea.
Il croit que nous avons tort.: He thinks we're wrong.
Croyez-vous que nous ayons tort ?: Do you think we're wrong ?

These two are the pair you will meet constantly, and they behave identically.

Certainty and Its Absence

Je suis certain qu'elle viendra.: I'm sure she'll come.
Je ne suis pas certain qu'elle vienne.: I'm not sure she'll come.
Il est évident que tu as raison.: It's obvious you're right.
Il n'est pas évident que tu aies raison.: It's not obvious you're right.

Anything that asserts certainty flips to the subjunctive as soon as the certainty is withdrawn.

Judgement and Opinion

Je trouve que ce film est trop long.: I think this film is too long.
Je ne trouve pas que ce film soit trop long.: I don't think this film is too long.
On dirait qu'il pleut.: It looks like it's raining.
Je ne dis pas que tu aies tort.: I'm not saying you're wrong.

Je ne dis pas que with the subjunctive is a standard way of conceding a point without agreeing.

Questions Without Inversion

Tu penses qu'il viendra ?: Do you think he'll come ?
Est-ce que tu crois qu'il ait raison ?: Do you think he's right ?
Pensez-vous que ce soit possible ?: Do you think that's possible ?
Vous trouvez que c'est normal ?: Do you think that's normal ?

A question asked with rising intonation usually keeps the indicative; a formal inverted question invites the subjunctive.

Why the Mood Moves

The rule looks arbitrary until you notice that it tracks whether the speaker is standing behind the statement.

An Affirmative Judgement Guarantees the Clause

Je pense que amounts to a mild assertion: the speaker is putting the content forward as true. Because it is being asserted, the clause behaves like any statement of fact and takes the indicative.

Je crois qu'il est déjà rentré.

I think he's already home.

Asserted → indicative.

Negation Removes the Guarantee

Je ne pense pas que leaves the content floating: nobody in the sentence is claiming it is true. The subjunctive is the mood for content nobody is vouching for.

Je ne crois pas qu'il soit déjà rentré.

I don't think he's home yet.

Withdrawn → subjunctive.

Questions Suspend the Guarantee Too

Asking whether you think something means the speaker is not asserting it either. Inverted questions in particular tend to take the subjunctive, because the register is already more careful.

Croyez-vous qu'elle veuille encore de ce poste ?

Do you think she still wants that job ?

Question → subjunctive available.

The Choice Carries Meaning

Keeping the indicative after a negated verb suggests you personally believe the clause anyway. Je ne pense pas qu'il est venu hints that he probably did; je ne pense pas qu'il soit venu takes no position at all.

Je ne dis pas qu'il a menti, je dis que c'est étrange.

I'm not saying he lied, I'm saying it's odd.

Indicative = you still believe it.

Some Neighbours Never Vary

Savoir que and il est certain que keep the indicative even when negated in the interrogative, and douter que and il est possible que take the subjunctive always. Only the middle band of judgement verbs varies.

Je ne sais pas s'il viendra, mais je doute qu'il vienne.

I don't know whether he'll come, but I doubt he will.

Doubt always subjunctive, knowledge never.

Common Mistakes with Variable Subjunctive

Incorrect: Je pense qu'il soit malade. — I think he's ill.

Correct: Je pense qu'il est malade. — I think he's ill.

Affirmative penser asserts the clause, so the indicative is required. Learners who have been told penser is a subjunctive verb apply it in exactly the case where it does not belong.

Incorrect: J'espère qu'il vienne. — I hope he comes.

Correct: J'espère qu'il viendra. — I hope he comes.

Espérer is the odd one out among verbs of wishing: affirmative, it takes the indicative, normally in the future. Souhaiter and vouloir take the subjunctive, which is where the confusion comes from.

Incorrect: Je ne suis pas sûr qu'il peut venir. — I'm not sure he can come.

Correct: Je ne suis pas sûr qu'il puisse venir. — I'm not sure he can come.

Negating être sûr removes the assertion, so the clause is no longer being claimed as true. The subjunctive puisse is what marks that in careful French.

Incorrect: Il est possible qu'il vient demain. — He may come tomorrow.

Correct: Il est possible qu'il vienne demain. — He may come tomorrow.

Il est possible que is not a variable trigger; it always takes the subjunctive, affirmative or not. Only il est probable, with its stronger claim, keeps the indicative.

The Two Moods Side by Side

Because the subjunctive is triggered by the same clause the indicative would occupy, the most useful table is a direct comparison. Look for the rows where the two columns are identical: those are the places the rule is invisible in speech.

Venir in Both Moods

Venir is the verb that appears in these clauses more than any other, and its two moods differ clearly in the singular.

Pronoun	indicatif (je pense que…)	subjonctif (je ne pense pas que…)
je / j'	viens	vienne
tu	viens	viennes
il / elle / on	vient	vienne
nous	venons	venions
vous	venez	veniez
ils / elles	viennent	viennent

The ils row is identical in both columns, so ils viennent gives no clue about which mood the speaker chose.

Être and Avoir in Both Moods

These two are the clearest, because no form is shared between the columns. Soit and ait are the loudest signals that a speaker has gone subjunctive.

Pronoun	être — indicatif	être — subjonctif	avoir — indicatif	avoir — subjonctif
je / j'	suis	sois	ai	aie
tu	es	sois	as	aies
il / elle / on	est	soit	a	ait
nous	sommes	soyons	avons	ayons
vous	êtes	soyez	avez	ayez
ils / elles	sont	soient	ont	aient

Que ce soit and qu'il y ait are so common after a negated judgement that they are worth learning as blocks.

Where the Difference Disappears

Regular -er verbs have identical indicative and subjunctive forms in four persons out of six, which is why the rule so often makes no audible difference.

Pronoun	parler — indicatif	parler — subjonctif	prendre — indicatif	prendre — subjonctif
je / j'	parle	parle	prends	prenne
tu	parles	parles	prends	prennes
il / elle / on	parle	parle	prend	prenne
nous	parlons	parlions	prenons	prenions
vous	parlez	parliez	prenez	preniez
ils / elles	parlent	parlent	prennent	prennent

Only nous and vous distinguish the two moods for parler, which is one reason the rule is drifting in modern speech.

Espérer, Sembler, and the Probability Scale

Three sets of expressions sit close to the variable verbs but follow slightly different habits, and mixing them up is easy.

Espérer

Unlike its English equivalent and unlike souhaiter, espérer takes the indicative when affirmative, usually with a future. Negated or questioned, the subjunctive appears.

J'espère qu'il fera beau demain.: I hope the weather will be nice tomorrow.
J'espère que tu vas bien.: I hope you're well.
Je n'espère pas qu'il pleuve.: I'm not hoping for rain.
Je souhaite qu'il fasse beau.: I wish for good weather. (always subjunctive)

Espérer with the indicative catches out almost everyone, because hoping feels like a textbook subjunctive trigger.

Sembler and paraître

Adding an indirect object pronoun anchors the impression in a person and brings back the indicative. Without one, the impression is impersonal and the subjunctive takes over.

Il me semble qu'elle a raison.: It seems to me she's right.
Il semble qu'elle ait raison.: It seems she's right.
Il paraît qu'ils déménagent.: Apparently they're moving.
Il ne semble pas qu'il y ait de problème.: There doesn't seem to be a problem.

Il paraît que is the exception in this group and keeps the indicative, because it reports hearsay as fact.

The probability scale

How likely something is decides the mood directly. High probability keeps the indicative; anything short of it moves to the subjunctive.

Il est probable qu'il viendra.: He'll probably come.
Il est peu probable qu'il vienne.: He's unlikely to come.
Il est possible qu'il vienne.: He may come.
Il se peut qu'il vienne.: He might come.

Probable takes the indicative and possible takes the subjunctive, which is the neatest illustration of the whole principle.
