Le plus-que-parfait et le conditionnel passé
Two compound past tenses that build on what you already know about passé composé and conditionnel. The plus-que-parfait is a past-of-the-past: it situates one past event before another ("I had already eaten when she arrived"). The conditionnel passé expresses past hypotheticals and regrets ("I would have come"). Both are formed exactly like the passé composé — auxiliary + past participle — except the auxiliary itself sits in a different tense.
Plus-que-parfait — formation
Recipe: take the auxiliary (avoir or être) in the imparfait, add the past participle. j'avais parlé = I had spoken. tu avais fini = you had finished. il était parti = he had left. The auxiliary choice and the participle agreement work exactly like in the passé composé (lessons 16-17). Verbs that take être in passé composé also take être here. Reflexive verbs always take être: je m'étais levé(e) = I had gotten up.
Plus-que-parfait — when to use it
Use the plus-que-parfait for an action that was already completed before another past action. Quand je suis arrivé, il était déjà parti. = When I arrived, he had already left. (His departure happened before my arrival.) Elle m'a dit qu'elle avait perdu ses clés. = She told me she had lost her keys. (Losing them happened before telling me.) It's also the si clause for Type 3 conditionals (lesson 28): Si j'avais su… = If I had known…
Conditionnel passé — formation
Recipe: take the auxiliary in the conditionnel présent, add the past participle. j'aurais parlé = I would have spoken. tu aurais fini = you would have finished. il serait parti = he would have left. nous serions venus = we would have come. Same auxiliary rules as passé composé. Same participle agreement (with être, the participle agrees with the subject; with avoir, only with a preceding direct object).
Conditionnel passé — when to use it
Three main uses. (1) Past regrets and missed opportunities: J'aurais aimé venir. = I would have liked to come. Tu aurais dû me dire. = You should have told me. (Note: devoir in conditionnel passé = 'should have'; pouvoir in conditionnel passé = 'could have'.) (2) The result clause of a Type 3 si: Si j'avais su, je serais venu. = If I had known, I would have come. (3) Reported speech / unverified claims in journalism: Le ministre aurait menti. = The minister allegedly lied. (English uses 'reportedly' / 'allegedly' here.)
Devoir, pouvoir, vouloir at the conditionnel passé
These three modal verbs at the conditionnel passé carry essential B1 meanings. j'aurais dû + infinitive = I should have ___ . Tu aurais dû partir plus tôt. = You should have left earlier. j'aurais pu + infinitive = I could have ___ . J'aurais pu t'aider, mais je ne savais pas. = I could have helped you, but I didn't know. j'aurais voulu + infinitive = I would have wanted to / I would have liked to. J'aurais voulu être là. = I would have liked to be there. (Stylistic alternative to j'aurais aimé.)
Quick comparison — three past tenses side by side
Take a moment to feel the difference. passé composé: completed past action — j'ai mangé = I ate / I have eaten. plus-que-parfait: action completed BEFORE another past action — j'avais mangé = I had eaten (before something else). conditionnel passé: hypothetical past — j'aurais mangé = I would have eaten. The auxiliary tense is the only thing that changes; the participle stays the same. Once you can conjugate avoir and être in three tenses, you've got three full compound paradigms.
