Le Conditionnel

The conditionnel is to the past what the futur simple is to the future. Where the futur projects an event forward in time, the conditionnel suspends it: je le ferais (I would do it) is the action lifted out of time, hypothetical, unrealised, polite, or under-verified.

It is one of the most useful tenses in French because it has four very different jobs, all served by the same conjugation. Once you have the form, you can do all four.

How to form it

The conditionnel uses the same stem as the futur simple plus the endings of the imparfait.

If you’ve learned the futur simple, the conditionnel is one step away.

Examples

parler (futur stem parler-)

être (futur stem ser-)

avoir (futur stem aur-)

The fifteen irregular stems from futur simple carry over here. Aller → irais, faire → ferais, voir → verrais, etc.

The four uses

1. Hypotheticals (the would tense)

The classic use. What you’d do if something were true.

Si j’avais le temps, je viendrais. — If I had the time, I would come. Si elle savait, elle partirait. — If she knew, she’d leave.

The structure is si + imparfait + conditionnel. The si-clause uses imparfait; the main clause uses conditionnel. (For past counterfactuals, use si + plus-que-parfait + conditionnel passé: si j’avais su, je serais venu — if I had known, I would have come.)

Never use conditionnel directly after si — si je viendrais is wrong. The condition is in imparfait or plus-que-parfait; only the consequence is in conditionnel.

2. Polite requests

The single most common use of the conditionnel in everyday French. The conditional softens a present-tense statement into something polite.

Je voudrais un café. — I would like a coffee. Pourriez-vous m’aider ? — Could you help me? Auriez-vous du pain ? — Would you have any bread?

Native speakers reach for je voudrais over je veux almost universally. Saying je veux un café is grammatical but reads as blunt or childish; je voudrais is the adult form. This single use justifies learning the conditionnel by week one of A2.

3. Reported speech (mapping a future into the past)

When you report what someone said about the future, the future shifts to conditionnel.

Il dit qu’il viendra. (Direct: he says he’ll come.) — He says he will come. Il a dit qu’il viendrait. (Reported: he said he’d come.) — He said he would come.

The futur simple of the original statement (viendra) becomes conditionnel (viendrait) when embedded in a reporting verb in the past. This is the same shift English does — will becomes would when reported.

Elle pensait qu’elle réussirait. — She thought she would succeed.

4. Unverified or hedged statements (the journalistic conditionnel)

This is the use most learners discover late. In French journalism and in cautious speech, the conditionnel signals that the speaker is reporting something unverified.

Selon des sources, le ministre aurait démissionné. According to sources, the minister has resigned. (Literally: would have resigned.)

This conditionnel journalistique is everywhere in French news. Le suspect serait armé (the suspect is reportedly armed). Trois personnes auraient été blessées (three people are reported injured). The conditionnel quietly disclaims responsibility for the truth of the statement. English uses reportedly or allegedly; French uses the conditional.

Past conditional (conditionnel passé)

The compound form: present conditional of avoir or être + past participle.

J’aurais parlé. — I would have spoken. Elle serait venue. — She would have come.

It’s used for past counterfactuals (the third conditional), past polite expressions of regret, and reported pasts.

J’aurais aimé venir. — I would have liked to come. Si tu avais demandé, je t’aurais aidé. — If you had asked, I would have helped you.

For agreement rules, see accord du participe passé — the conditional uses the same auxiliaries and the same agreement system as the passé composé.

How writers use it

The conditionnel is the tense of unrealised possibility, which makes it indispensable to any novelist whose characters wonder, regret, or suspect.

In Madame Bovary, the conditionnel is the grammar of Emma’s life. Her unrealised romantic ambitions, her imagined alternative selves, her counterfactual regrets — Flaubert renders all of them in conditional. Si elle avait été…, elle serait…, elle aurait… The book contains some of the most concentrated use of the conditional in French literature.

In Dumas, the conditional is the tense of plotting and counter-plotting. Edmond Dantès calculates what would happen if his enemies did this or that, and the elaborate revenge sequences play out partly in conditional. The complete patience of the Count is grammatical: he constructs futures in conditional and waits to make them real.

In Saint-Exupéry’s Le Petit Prince, the conditional appears mostly in its polite-request form. The prince says je voudrais to every adult he meets. The fox uses it to propose, gently, that the prince tame him.

What you don’t need to do

You don’t need to memorise the imparfait endings separately to form the conditionnel — they’re the same six endings. If you know the imparfait, the only new piece is the futur stem.

You don’t need to translate would into French every time. English would maps to conditional in some uses, to imparfait in habitual sense (we would walk to school), and sometimes to nothing. Read the meaning, not the word.

You don’t need to use the journalistic conditional in your own writing. Recognise it when you see it; in your own French, just stick with verifiable claims.

Common confusions

• Si + conditional is wrong. Si j’aurais le temps is a common and notorious error among French children themselves. Always si j’avais le temps, je viendrais.
• Je voudrais, not je veux. Always reach for je voudrais in service contexts — restaurants, shops, polite asks. Je veux is for children and emergencies.
• Past conditional has agreement rules. Elle serait partie, je l’aurais vue. The same rules as passé composé apply.
• The journalistic conditional is real. When you read a French newspaper and see le président aurait dit, that’s not literally the president would have said. It’s the president reportedly said. Don’t be confused.

Where you’ll meet it in the library

The conditional appears in every French book at every level. Especially central in:

• Madame Bovary (B2) — the tense of Emma’s interior life. Reading any chapter from her point of view will yield half a dozen conditionnels.
• Le Comte de Monte-Cristo (B2) — Dumas’s plotting. The Count’s calculations of what would happen are in conditional throughout.
• Le Petit Prince (A1) — the polite-request form. Almost every dialogue in which the prince speaks to an adult contains a je voudrais or pourriez-vous.
• L’Étranger (B1) — sparser, but Camus uses conditional at the trial, where the prosecutor projects what Meursault would have done in alternative scenarios.
• Any dialogue containing a request, a proposal, or a hedged claim. Conditional is the grammar of polite social negotiation in French.
