French Conditional Tense: Complete Guide with Examples
Introduction: What Is the French Conditional?
The French conditional (le conditionnel) is a verb mood used to express actions that are hypothetical, uncertain, or dependent on certain conditions. If you want to understand the French conditional explained simply: it's equivalent to "would" in English—as in "I would go" or "she would like."
The conditional is essential for polite requests, expressing wishes, discussing hypothetical situations, and reporting unconfirmed information. When you learn French conditional, you unlock the ability to speak with greater nuance and politeness.
Formation: French Conditional Conjugation
Understanding French conditional conjugation is straightforward once you know the pattern. The conditional is formed by taking the future stem of a verb and adding the imperfect endings.
The Formula
Future stem + imperfect endings (-ais, -ais, -ait, -ions, -iez, -aient)
For regular verbs:
- -er verbs: Use the infinitive as the stem (parler → parler-)
- -ir verbs: Use the infinitive as the stem (finir → finir-)
- -re verbs: Drop the final -e (vendre → vendr-)
Regular Verb Conjugations
| Subject | PARLER (to speak) | FINIR (to finish) | VENDRE (to sell) |
|---|---|---|---|
| je | parlerais | finirais | vendrais |
| tu | parlerais | finirais | vendrais |
| il/elle/on | parlerait | finirait | vendrait |
| nous | parlerions | finirions | vendrions |
| vous | parleriez | finiriez | vendriez |
| ils/elles | parleraient | finiraient | vendraient |
Irregular Stems
Many common verbs have irregular future stems, which carry over to the conditional:
| Infinitive | Irregular Stem | Conditional (je) |
|---|---|---|
| être (to be) | ser- | je serais |
| avoir (to have) | aur- | j'aurais |
| aller (to go) | ir- | j'irais |
| faire (to do/make) | fer- | je ferais |
| pouvoir (can) | pourr- | je pourrais |
| vouloir (to want) | voudr- | je voudrais |
| devoir (must) | devr- | je devrais |
| savoir (to know) | saur- | je saurais |
| venir (to come) | viendr- | je viendrais |
| voir (to see) | verr- | je verrais |
Usage: How to Use Conditional in French
Knowing how to use conditional in French requires understanding its various contexts. Here are the main uses:
1. Polite Requests and Wishes
The conditional softens requests and makes them more polite. This is one of the most practical reasons to learn French conditional.
- Je voudrais un café, s'il vous plaît. — I would like a coffee, please.
- Pourriez-vous m'aider? — Could you help me?
2. Hypothetical Situations (with "si" clauses)
The conditional appears in the result clause of hypothetical sentences. The "si" (if) clause uses the imperfect tense.
- Si j'avais de l'argent, j'achèterais une maison. — If I had money, I would buy a house.
3. Future in the Past
When reporting what someone said about the future from a past perspective:
- Il a dit qu'il viendrait demain. — He said he would come tomorrow.
4. Unconfirmed Information
In journalism and formal contexts, the conditional indicates unverified claims:
- Le président serait malade. — The president is reportedly sick.
5. Giving Advice
Using "devoir" in the conditional to suggest what someone should do:
- Tu devrais étudier davantage. — You should study more.
French Conditional Examples
Here are practical French conditional examples to help solidify your understanding:
1. J'aimerais voyager en France cet été.

2. Si tu étais là, nous pourrions parler ensemble.
If you were here, we could talk together.
3. Nous aurions besoin de plus de temps pour finir ce projet.

4. Il faudrait que tu arrives plus tôt.
You would need to arrive earlier.
5. Qu'est-ce que tu ferais à ma place?
What would you do in my place?
6. Elle a promis qu'elle téléphonerait ce soir.
She promised she would call this evening.
7. Selon les témoins, l'accident aurait eu lieu vers midi.
According to witnesses, the accident reportedly happened around noon.
Common Mistakes
When learning French conditional conjugation, watch out for these frequent errors:
1. Confusing Conditional with Future Tense
Both use the same stem, but the endings differ. The future uses -ai, -as, -a, -ons, -ez, -ont, while the conditional uses -ais, -ais, -ait, -ions, -iez, -aient.
- Future: Je parlerai (I will speak)
- Conditional: Je parlerais (I would speak)
2. Using Conditional in the "Si" Clause
Never use the conditional after "si" in hypothetical sentences. Use the imperfect instead.
- Incorrect: Si j'aurais le temps...
- Correct: Si j'avais le temps, je viendrais.
3. Forgetting Irregular Stems
Students often apply regular conjugation rules to irregular verbs. Memorize the common irregular stems listed above.
- Incorrect: Je allerais
- Correct: J'irais
4. Mixing Up -ais and -ait Spellings
Remember: je and tu both take -ais, while il/elle/on takes -ait. They sound identical but are spelled differently.
5. Overusing the Conditional
English speakers sometimes use the conditional where French requires the present or subjunctive. For example, after "quand" (when) referring to the future, French uses the future tense, not conditional.
- Incorrect: Quand tu viendrais, appelle-moi.
- Correct: Quand tu viendras, appelle-moi. (When you come, call me.)
