If-clauses: Imperfect + Conditional (Second Conditional)
B1Si Clauses: Imparfait + Conditional (Second Conditional)
This article explains the French "si" clause pattern that uses the imparfait in the "si" (if) part and the conditionnel present in the result part. This structure expresses unreal or hypothetical situations in the present or future — the equivalent of the English second conditional ("If I were..., I would..."). Below you will find clear explanations, formation rules, many examples, common mistakes, and a short glossary.
What does this structure express?
Meaning and English equivalent
The pattern Si + imparfait, conditionnel présent describes a hypothetical, unlikely, or contrary-to-fact situation in the present or future. In English it corresponds to the second conditional:
- English pattern: If + past simple, would + base verb
- Example: "If I had a car, I would drive to the beach."
- French pattern: Si + imparfait, conditionnel présent
- Example: "Si j'avais une voiture, je conduirais à la plage."
When do I use it?
Use this structure when:
- You imagine a situation that is not true now (contrary to reality):
- "Si j'étais riche, j'achèterais une maison." (I am not rich now.)
- You describe a hypothetical future that is unlikely:
- "Si nous avions plus de temps, nous voyagerions davantage." (We probably don't.)
- You soften a request or suggestion (polite or tentative):
- "Si vous pouviez m'aider, ce serait gentil." (More polite than direct demand.)
How do I form it?
Step 1 — Form the imparfait (for the si clause)
To form the imparfait for most verbs:
1. Take the present-tense "nous" form.
2. Remove "-ons" to find the stem.
3. Add imparfait endings: -ais, -ais, -ait, -ions, -iez, -aient.
Examples:
- parler -> nous parlons -> stem parl- -> je parlais, tu parlais, il parlait, nous parlions, vous parliez, ils parlaient.
- finir -> nous finissons -> stem finiss- -> je finissais, etc.
- prendre -> nous prenons -> stem pren- -> je prenais, etc.
- être is irregular: nous sommes -> stem ét- -> j'étais, tu étais, il était, nous étions, vous étiez, ils étaient.
Step 2 — Form the conditionnel présent (for the result clause)
To form the conditionnel présent:
1. Start with the future stem (usually the infinitive for regular verbs; for -re verbs drop the final "-e").
2. Add the imparfait endings: -ais, -ais, -ait, -ions, -iez, -aient.
Examples:
- parler -> stem parler- -> je parlerais, tu parlerais, il parlerait, nous parlerions, vous parleriez, ils parleraient.
- finir -> finir- -> je finirais.
- vendre (drop final e) -> vendr- -> je vendrais.
- aller (irregular) -> ir- -> j'irais.
- être -> ser- -> je serais.
- avoir -> aur- -> j'aurais.
- faire -> fer- -> je ferais.
- pouvoir -> pourr- -> je pourrais.
Note: Conditional endings are exactly the imparfait endings.
Putting them together — the formula
- Formula: Si + imparfait, conditionnel présent
- Example: "Si + j'avais (imparfait), je + voyagerais (conditionnel)."
- "Si j'avais le temps, je voyagerais beaucoup."
Examples (many varieties)
Simple hypothetical / contrary-to-present reality
- "Si j'avais un million d'euros, je ferais le tour du monde."
- (If I had a million euros, I would travel around the world.)
- "Si elle était plus gentille, il l'aimerait."
- (If she were kinder, he would like her.)
- "S'ils habitaient plus près, ils viendraient plus souvent."
- (If they lived closer, they would come more often.)
Polite requests or softened suggestions
- "Si vous pouviez attendre une minute, je reviendrais tout de suite."
- (If you could wait a minute, I would come back right away.)
- "Si tu voulais, tu pourrais essayer cette méthode."
- (If you wanted, you could try this method.)
Using modal meanings (would / could / should) in French
- "Si j'avais plus de temps, je pourrais t'aider."
- (If I had more time, I could help you.)
- "Si elle avait le diplôme, elle devrait postuler."
- (If she had the degree, she should apply.)
Negative and question forms
- "Si je n'avais pas peur, je sauterais."
- (If I weren't afraid, I would jump.)
- "Si tu venais demain, pourrais-tu m'aider?"
- (If you came tomorrow, could you help me?)
Common verbs with examples
- être: "Si j'étais toi, je m'excuserais." (If I were you, I'd apologize.)
- avoir: "Si nous avions plus d'argent, nous achèterions une maison." (If we had more money, we'd buy a house.)
- aller: "Si elle allait en France, elle parlerait mieux français." (If she went to France, she'd speak French better.)
- faire: "Si tu faisais plus d'exercice, tu te sentirais mieux." (If you exercised more, you'd feel better.)
Common mistakes and how to avoid them
1) Never use the conditionnel in the "si" clause
Wrong: "Si j'aurais de l'argent, j'achèterais une voiture."
Correct: "Si j'avais de l'argent, j'achèterais une voiture."
Explanation: In French you must not put the conditional in the "si" clause. The "si" clause takes imparfait (for this pattern), and the main clause takes the conditional present.
2) Don't confuse with the real/possible condition (Si + présent + futur)
- Real/possible (likely): "Si j'ai le temps, j'irai au cinéma." (If I have time, I will go.)
- Hypothetical/unreal: "Si j'avais le temps, j'irais au cinéma." (If I had the time, I would go.)
Choose imparfait + conditionnel when the condition is imagined or unlikely now.
3) Avoid mixing tense patterns
- Past unreal (different pattern): "Si j'avais su, je ne serais pas venu." uses plus-que-parfait + conditionnel passé (not imparfait + conditionnel).
Comparison with other "si" structures
Si + présent -> futur / présent / impératif (real possibility)
- "Si tu étudies, tu réussiras." (If you study, you will succeed.) — possible, likely.
Si + imparfait -> conditionnel présent (unreal/hypothetical now or future) — THIS ARTICLE
- "Si tu étudiais, tu réussirais." (If you studied, you would succeed.) — not true now, hypothetical.
Si + plus-que-parfait -> conditionnel passé (counterfactual past)
- "Si tu avais étudié, tu aurais réussi." (If you had studied, you would have passed.) — refers to a past situation that did not happen.
Quick reference / Cheat sheet
- Formula: Si + imparfait, conditionnel présent
- Imparfait formation: nous present -> drop -ons -> add -ais, -ais, -ait, -ions, -iez, -aient
- Conditionnel présent: future stem (often infinitive) + imparfait endings
- Use it for present/future situations that are imagined, unlikely, or contrary to reality.
Glossary (short)</b]
Si clause — The part of the sentence introduced by "si" (if). In this pattern it uses the imparfait.
Imparfait — A French past tense used for ongoing or habitual actions in the past; here it expresses an imagined or unreal present/future condition.
Conditionnel présent — The tense that expresses "would/could/should"; formed from the future stem + imparfait endings.
Second conditional — English grammar term for "If + past, would + verb"; equivalent in meaning to Si + imparfait, conditionnel présent in French.
Summary
- Use Si + imparfait + conditionnel présent to talk about unreal or unlikely situations now or in the future.
- Form the imparfait from the nous present stem + imparfait endings.
- Form the conditionnel from the future stem + the same imparfait endings.
- Watch out for the common error of putting the conditional in the "si" clause — it must be the imparfait.
If you keep the formula Si + imparfait, conditionnel présent in mind, and practice forming imparfait and conditionnel stems, you will be able to express a wide range of hypothetical ideas in French.
