Je ferai or je ferais? French future and conditional compared
Compare future commitments, hypothetical results and polite requests through paired examples, a work-planning scene and four questions.
Je ferai means “I will do”; je ferais means “I would do”. The future presents a later action; the conditional can frame a hypothetical result, advice or a softened request. Choose the meaning, then the ending.

| Subject | Future | Conditional |
|---|---|---|
| je | ferai | ferais |
| tu | feras | ferais |
| il / elle / on | fera | ferait |
| nous | ferons | ferions |
| vous | ferez | feriez |
| ils / elles | feront | feraient |
A final -s distinguishes the two je forms. With nous and vous, look for -ions and -iez in the conditional. Some speakers pronounce ferai and ferais alike; in writing, use the sentence’s purpose and the written ending.

Si nous avons le temps, nous participerons.
If we have time, we will take part.
An open condition: present after si, future in this result.
Si nous avions le temps, nous participerions.

A future can include uncertainty: Je viendrai peut-être means “I may come”. For a request now, Pourriez-vous m’aider ? means “Could you help me?” For future availability, Pourrez-vous m’aider lundi ? asks whether the person will be able to help on Monday.
