The French Conditional Tense (Conditionnel): When and How to Use It

Some tenses live mostly in textbooks. The conditionnel isn’t one of them. Every time you soften a request, ask a stranger for help, or say what you’d do in a different world, you reach for it. Order a coffee, ask for directions, tell a friend what you’d do with more time — the conditionnel shows up constantly in real conversation, which is exactly why it’s one of the two tenses selected by default when you start practicing on Conjugaison.ca.

The shortcut: you already know most of it

Here’s the good news: the conditionnel isn’t a new set of forms to memorize from scratch. It’s a remix of two tenses you likely already know.

Stem: the same stem used for futur simple — the infinitive itself for most verbs, the infinitive minus -e for -re verbs, or the irregular future stem for irregular verbs.

Endings: the imparfait endings — -ais, -ais, -ait, -ions, -iez, -aient.

Put them together:

parler → futur je parlerai → conditionnel je parlerais
avoir → futur j’aurai → conditionnel j’aurais
être → futur je serai → conditionnel je serais
aller → futur j’irai → conditionnel j’irais

If a verb has an irregular future stem, that irregularity carries straight over into the conditionnel — no new exceptions to learn. Know your futur stems and your imparfait endings, and the conditionnel is nearly free.

Everyday politeness

The single most common real-world use of the conditionnel is softening a request or desire. Compare:

Je veux un café. (I want a coffee.) — blunt, almost demanding
Je voudrais un café. (I would like a coffee.) — polite, normal, what you’ll actually hear in a café

The same shift happens with pourriez-vous (could you — from pouvoir) and j’aimerais (I would like — from aimer):

Pourriez-vous m’aider ? (Could you help me?)
J’aimerais réserver une table pour deux. (I’d like to reserve a table for two.)

None of these are optional formalities — they’re the default way French speakers make requests. Using je veux where je voudrais belongs isn’t wrong grammatically, it just sounds abrupt.

Hypotheticals with “si”

The conditionnel also expresses what would happen under a different set of circumstances, typically paired with a si (if) clause in the imparfait:

Si j’avais le temps, je voyagerais plus. (If I had time, I would travel more.)
Si tu me le demandais, je t’aiderais. (If you asked me, I’d help you.)

The pattern: si + imparfait, then conditionnel in the result. This is just one of French’s several si-clause structures, but it’s the one that pairs directly with what you just learned above — no extra forms needed.

There’s also a distinctly French use worth knowing: news reports use the conditionnel to flag information that hasn’t been confirmed. Le suspect serait à Paris doesn’t mean “the suspect would be in Paris” — it means “the suspect is reportedly in Paris,” with the tense itself signaling that the claim is unverified. You’ll see this constantly in headlines and news broadcasts.

Conditionnel passé: regret and hypothetical past

The conditionnel passé is a compound tense: conditionnel of avoir or être + past participle. It’s how French expresses regret or talks about something that could have happened but didn’t:

J’aurais dû étudier. (I should have studied.)
Elle serait venue si elle avait pu. (She would have come if she could have.)
Nous aurions aimé rester plus longtemps. (We would have liked to stay longer.)

If you already know the passé composé, this costs you nothing new — just swap the present-tense avoir/être for its conditionnel form and keep the same past participle.

Ready to put it into practice? Head to /verbs to make sure Conditionnel présent and Conditionnel passé are selected — présent is on by default for good reason — then drill them on the flashcards until je voudrais and j’aurais aimé come out without a second thought.
