Conditionnel présent — The Conditional

Express politeness, hypothetical situations, and conditions with si + imparfait

Formation: Future Stem + Imparfait Endings

The conditional uses the same stems as the future simple (usually the full infinitive for regular verbs) plus the endings of the imparfait: -ais, -ais, -ait, -ions, -iez, -aient.

vousparleriezfiniriezattendriez
ils/ellesparleraientfiniraientattendraient

Note on -re verbs: drop the final -e before adding endings: attendre → attendr- → j'attendrais.

Irregular Stems — Same as Future

The irregular conditional stems are identical to the irregular future stems. These must be memorised:

fairefer-il ferait
pouvoirpourr-il pourrait

Use 1: Polite Requests and Suggestions

The conditional softens requests, making them more polite. It is essential for formal and social contexts:

  • Je voudrais un café, s'il vous plaît. (I would like a coffee.) — much more polite than: Je veux un café.
  • Pourriez-vous répéter? (Could you repeat that?) — polite form of pouvoir
  • Tu devrais parler à ton professeur. (You should talk to your teacher.) — devoir conditional = should
  • On pourrait aller au cinéma ce soir. (We could go to the cinema tonight.) — suggestion
  • Auriez-vous l'heure? (Would you have the time?) — formal request

Use 2: Si + Imparfait + Conditionnel

For hypothetical situations in the present or future (things that are unlikely or imaginary), use: si + imparfait in the condition, conditionnel in the result.

Si clause (imparfait)Result clause (conditionnel)
Si j'avais de l'argent,j'achèterais une voiture.
(If I had money,)(I would buy a car.)
Si elle était là,elle t'aiderait.
(If she were here,)(she would help you.)
Si vous vouliez,vous pourriez partir plus tôt.
(If you wanted to,)(you could leave earlier.)

Rule: Never put the conditional in the si clause. Si is always followed by imparfait (for hypothetical), never by conditional.

Use 3: Unconfirmed Information (Journalistic Conditional)

In French journalism and formal speech, the conditional is used to report unverified information — translating as 'reportedly' or 'allegedly':

  • Le président serait en visite à Paris. (The president is reportedly visiting Paris.)
  • L'accident aurait fait trois blessés. (The accident reportedly left three injured.)
  • Ce médicament pourrait guérir la maladie. (This drug could allegedly cure the disease.)

This use signals that the speaker is not personally vouching for the truth of the statement — it is attributed information.

Common Mistakes

AvoidUseWhy
Si j'aurais de l'argent…Si j'avais de l'argent…Never use the conditional after si in a hypothetical clause. Si + imparfait (not conditional).
je voudrais → je voudraitje voudraisThe ending for je is -ais (not -ait). Je voudrais (I would like). Il voudrait (he would like).
attendrais (wrong stem: attenderais)j'attendraisFor -re verbs, drop the final -e: attendre → attendr-. Add -ais: j'attendrais (not attenderais).
devrais = I must (present)devrais = I should (conditional)Je dois = I must (present). Je devrais = I should (conditional). They are different tenses with different meanings.
