Conditional Sentences with Contrary-to-Fact Conditions
Type 3 or contrary-to-fact conditional sentences express impossible or unreal past situations—something that did not happen. They use si (if) + plus-perfect subjunctive (had + past participle) in the condition, and conditional perfect in the consequence. These sentences let you imagine alternative histories.
Contrary-to-fact conditionals (Type 3) describe imaginary past events: si + plus-perfect subjunctive → conditional perfect. Example: Si j'avais étudié, j'aurais réussi (If I had studied, I would have passed).

FAQ
What is the plus-perfect subjunctive?
It combines avoir/être in imperfect subjunctive with a past participle: j'eusse étudié (archaic) or j'avais étudié (modern). It expresses an unreal past condition.
Can you use je eusse instead of j'avais?
Eusse is archaic/literary. Modern French uses j'avais étudié. Eusse appears in formal or historical writing: Si j'eusse su (If I had known—literary style).
What if both clauses involve different people?
The si clause subject and result clause subject can differ: Si tu avais étudié, j'aurais été fier (If you had studied, I would have been proud).
Is Type 3 always about regret?
Not always regret. It can express curiosity: Si tu avais dit la vérité, aurais-tu été heureux? (If you had told the truth, would you have been happy?). It explores unreal pasts.
