Pouvoir Conjugation: Every Tense With Examples

Pouvoir means can and to be able to, and you need it in your first week of French. You use it to ask permission (Je peux entrer ?), to offer help (Je peux vous aider ?), to talk about what is possible (Ça peut arriver) and, in the conditional, to ask for things politely (Pourriez-vous répéter ?).

The problem is that it changes shape all the time: peux, pouvons, peuvent, pu, pourrai, puisse. This page gives you the full pouvoir conjugation in every tense you need, with simple pronunciation hints, the puis-je rule, the difference between pouvoir and savoir, 10 example sentences and a short practice set.

Pouvoir conjugation in the present tense

Learn these six forms first. Larousse classifies pouvoir as an irregular verb of the third group.

The University of Texas French grammar calls pouvoir a boot verb, like vouloir. Draw a line around je, tu, il and ils on the table: those four forms keep the peu- vowel and make the shape of a boot. Only nous and vous switch to pou-.

Notice the spelling too. Je peux and tu peux end in x, not s. Il peut ends in t. All three sound exactly the same.

Tip from class: say ils peuvent with a clear "v" at the end. If you swallow it, ils peuvent (they can) sounds like il peut (he can), and your listener loses track of who you mean.

Puis-je or peux-je? The question form

This is the detail most textbooks skip. Larousse confirms that je peux and je puis are both correct. Je puis now appears only in very formal French, as in je ne puis faire autrement (I cannot do otherwise).

But there is one place where puis is required: inverted questions. Larousse is clear that puis-je replaces je peux when the subject comes after the verb.

• Puis-je vous aider ? May I help you? ✔
• Peux-je vous aider ? ✘ (never correct)

In everyday conversation, you rarely invert with je. You have two easier options:

• Je peux vous aider ? (rising intonation, very common)
• Est-ce que je peux m'asseoir ? May I sit down? (the University of Texas example)

You will hear Puis-je… from hotel staff, in formal emails and in Canadian government offices. If you want the full picture of how questions work, see our guide on asking questions in French.

Pouvoir in the passé composé: j'ai pu

Larousse lists pouvoir as a verb conjugated with avoir. The past participle is pu, and Larousse gives the same form for masculine, feminine, singular and plural, so it never takes an extra e or s.

The most useful sentence here is the negative: Je n'ai pas pu venir. (I couldn't come.) You will use it every time you miss a meeting.

Pouvoir in the imparfait: je pouvais

Take nous pouvons, drop -ons, and add the imparfait endings.

J'ai pu or je pouvais?

English says "could" for both, but French separates them.

• J'ai pu = one event that actually happened. J'ai pu parler au directeur. I managed to talk to the manager (and I did).
• Je pouvais = a background ability or a general situation. Quand j'étais petite, je pouvais lire pendant des heures. When I was little, I could read for hours.

In the negative, the difference matters even more. Je ne pouvais pas dormir describes a long night. Je n'ai pas pu dormir says sleep never came. Our article on passé composé vs imparfait shows the same logic with other verbs.

Pouvoir in the future: je pourrai

The future stem is irregular: pourr-, with a double r. Larousse gives:

French has no "will can", so je pourrai covers it: Je pourrai t'appeler demain. (I'll be able to call you tomorrow.)

Pouvoir in the conditional: je pourrais

Same stem, imparfait endings. This is the form you need most for polite requests.

The University of Texas grammar notes that modal verbs often appear in the conditional to make requests more polite. Compare:

• Vous pouvez répéter ? Can you repeat? (fine with friends)
• Pourriez-vous répéter, s'il vous plaît ? Could you repeat, please? (shops, offices, your child's teacher)

Tip from class: je pourrai (future) and je pourrais (conditional) sound almost the same, poo-RAY and poo-REH. In writing, ask yourself "will" or "would/could"? "Will" gets no s.

Pouvoir in the subjunctive: que je puisse

The subjunctive uses a completely new stem, puiss-, for every person.

You meet it after expressions of wish or doubt: Je ne crois pas qu'il puisse venir. (I don't think he can come.) For when to use the subjunctive in general, read the French subjunctive explained simply.

No imperative

Larousse states that pouvoir has no imperative and no passive. You can't order someone to "be able". To encourage someone, say Tu peux le faire ! (You can do it!).

Pouvoir vs savoir: can or know how?

English uses "can" for both, so this is one of the most common mix-ups I hear.

• Savoir + infinitive = a skill you learned. Larousse defines savoir nager as having the ability, after study and practice, to do an activity.
• Pouvoir + infinitive = you are able or allowed right now.

Quick test: if you could say "know how to" in English, use savoir.

In short

Pouvoir is a boot verb: peu- for je, tu, il and ils, pou- for nous and vous, pourr- in the future and conditional, puiss- in the subjunctive. It always takes avoir (j'ai pu), has no imperative, and becomes puis-je in inverted questions. Next, compare it with être and faire, then see where it ranks among the most common French verbs.
