Use the futur simple when the speaker presents an action as expected or planned in the future; use the conditionnel when the action depends on a condition, is hypothetical, is reported from a past viewpoint, or softens a request. Je partirai means I will leave; je partirais means I would leave. The forms look similar because the conditionnel uses futur stems plus imparfait endings, but the meaning changes from future certainty to conditional possibility.
will / going to happen → futur · would / could happen → conditionnel
The futur simple points forward from now: it presents the action as planned, predicted, promised, or expected. The conditionnel points to a possible world: the action would happen if another condition were true, or it is softened because the speaker does not want to sound too direct. This difference matters more than the English translation, because English sometimes uses would for repeated past habits, but French conditionnel is not a general past-habit tense.
A fast spelling check helps too: futur endings are -ai, -as, -a, -ons, -ez, -ont; conditionnel endings are -ais, -ais, -ait, -ions, -iez, -aient. Je parlerai and je parlerais sound identical for many speakers, but they are not interchangeable in writing.
Demain, je partirai à sept heures.
Tomorrow, I will leave at seven.
expected future
Si j'avais plus de temps, je partirais plus tôt.
If I had more time, I would leave earlier.
hypothetical result
Nous vous répondrons avant vendredi.
We will reply before Friday.
promise / commitment
Pourriez-vous me répondre avant vendredi ?
Could you reply before Friday?
polite request
past reporting verb + future idea → conditionnel
The conditionnel also works as future seen from the past. If someone said on Monday, je viendrai demain, and you report it later, French shifts the future into the conditionnel: il a dit qu'il viendrait le lendemain. The event may still have happened; the conditionnel here does not mean unreal. It means the future was viewed from an earlier past moment.
This use is essential in indirect speech, news style, and formal summaries. It explains why a sentence like le ministre a annoncé qu'il présenterait un projet de loi is not necessarily conditional. It can simply report a future promise from a past announcement.
Elle promet qu'elle viendra.
She promises that she will come.
present viewpoint → future
Elle a promis qu'elle viendrait.
She promised that she would come.
past viewpoint → conditional
Il pense qu'il réussira.
He thinks he will succeed.
Il pensait qu'il réussirait.
He thought he would succeed.
| Meaning | Use | Example |
|---|---|---|
| future plan | futur simple | Je réserverai les billets ce soir. |
| prediction | futur simple | Il pleuvra demain. |
| promise / commitment | futur simple | Nous vous contacterons rapidement. |
| hypothetical result | conditionnel | Je réserverais les billets si j'avais l'argent. |
| polite request | conditionnel | Je voudrais deux places. |
| advice | conditionnel | Tu devrais vérifier l'adresse. |
| future from a past viewpoint | conditionnel | Il a dit qu'il partirait tôt. |
Do not put the conditionnel after si in standard conditional clauses. French says si j'avais le temps, je viendrais, not si j'aurais le temps. The conditionnel belongs in the result clause; the si-clause uses imparfait for present hypotheticals and plus-que-parfait for past hypotheticals.
Do not confuse je parlerai and je parlerais in writing. The first is future; the second is conditional. In a formal email, je vous enverrai le document promises action. Je vous enverrais le document implies a condition or softens the commitment and may sound uncertain if no condition is stated.
English would in childhood stories often translates as imparfait, not conditionnel: every summer we would visit my grandparents = chaque été, nous rendions visite à mes grands-parents. Use conditionnel only when would means would happen, could happen, or polite softening.
Think of the futur as a straight arrow and the conditionnel as an arrow with a hinge. The futur points directly toward a future event. The conditionnel bends through another condition, a past viewpoint, or politeness. If the sentence needs a hidden if, a past he said that, or a softer request, use conditionnel. If it is a direct future plan, use futur.
In TEF/TCF writing, futur vs conditionnel controls tone. Use futur simple for concrete commitments in a formal letter: je vous transmettrai les documents, nous organiserons une réunion. Use conditionnel for polite requests and proposals: je souhaiterais obtenir un remboursement, il serait préférable de reporter la réunion. In speaking, conditionnel is a quick politeness upgrade: je voudrais, pourriez-vous, ce serait mieux. But avoid conditionnel after si, because si j'aurais is one of the fastest ways to signal unstable B1 grammar.
Je parlerai is futur simple: I will speak. Je parlerais is conditionnel: I would speak. They may sound the same in speech, but the spelling changes the meaning in writing.
Not in standard conditional clauses. Say si j'avais le temps, je viendrais, not si j'aurais le temps. The conditionnel goes in the result clause.
Because French shifts future viewed from the past into the conditionnel: il dit qu'il viendra becomes il a dit qu'il viendrait. This does not necessarily mean the action is unreal.
Use futur for your commitments and conditionnel for requests or suggestions: je vous enverrai le dossier, but je souhaiterais recevoir une confirmation.
