The imperfect subjunctive: recognition
Form and use in literary and formal texts.
1. A Tense You Read, Not One You Produce
The imperfect subjunctive (le subjonctif imparfait) is a tense that has virtually disappeared from spoken French and from most informal writing. It survives in three domains: classical and nineteenth-century literature, formal administrative prose, and deliberately elevated registers (speeches, certain journalism). At C1, your primary objective is to recognise it without being confused by it when it appears in reading texts, and to understand what grammatical function it is performing. Producing it actively is not required at this level, though knowing its forms will help you avoid mistaking it for another tense.
✓ Recognise the imperfect subjunctive forms in a text
✓ Understand that it replaces the present subjunctive after a past main verb
✓ Know which forms look unusual enough to cause reading confusion
✗ Not required: active production in writing or speech
2. Why It Existed: The Logic of the Subjunctive Sequence
In classical French grammar, the sequence of tenses in the subjunctive was strictly observed. Just as the indicative adjusts its tense according to the main verb's tense (as seen in the concordance des temps), the subjunctive had its own sequence:
| Main clause tense | Subordinate subjunctive: simultaneous or posterior | Subordinate subjunctive: anterior |
|---|---|---|
| Present / Future | Present subjunctive (subjonctif présent) | Past subjunctive (subjonctif passé) |
| Past / Conditional | Imperfect subjunctive (subjonctif imparfait) | Pluperfect subjunctive (subjonctif plus-que-parfait) |
Il voulait que tu viennes. (present subjunctive after a past main verb)
Classical / formal French (strict sequence):
Il voulait que tu vinsses. (imperfect subjunctive, simultaneous with past main verb)
Today, the present subjunctive has taken over in almost all contexts, even after past main verbs. The imperfect subjunctive persists only in very formal or literary registers.
3. Formation
The imperfect subjunctive is formed from the passé simple stem (the third person singular of the passé simple), with a characteristic set of endings. This is why recognising the passé simple is a prerequisite.
The endings are: -sse, -sses, -ˆt, -ssions, -ssiez, -ssent
Note the circumflex accent on the 3rd person singular (il / elle / on): this is distinctive.
-er verbs: parler (passé simple: il parla → stem: parl-a-)
| Person | Imperfect subjunctive |
|---|---|
| que je | parlasse |
| que tu | parlasses |
| qu'il / qu'elle | parlât |
| que nous | parlassions |
| que vous | parlassiez |
| qu'ils / qu'elles | parlassent |
-ir verbs: finir (passé simple: il finit → stem: fini-)
| Person | Imperfect subjunctive |
|---|---|
| que je | finisse |
| que tu | finisses |
| qu'il / qu'elle | finît |
| que nous | finissions |
| que vous | finissiez |
| qu'ils / qu'elles | finissent |
-re verbs: prendre (passé simple: il prit → stem: pri-)
| Person | Imperfect subjunctive |
|---|---|
| que je | prisse |
| que tu | prisses |
| qu'il / qu'elle | prît |
| que nous | prissions |
| que vous | prissiez |
| qu'ils / qu'elles | prissent |
Key irregular verbs
| Verb | Passé simple (3rd sg.) | Imperfect subj. (3rd sg.) | Other forms (1st sg.) |
|---|---|---|---|
| être | fut | fût | fusse |
| avoir | eut | eût | eusse |
| faire | fit | fît | fisse |
| aller | alla | allât | allasse |
| voir | vit | vît | visse |
| venir | vint | vînt | vinsse |
| savoir | sut | sût | susse |
| pouvoir | put | pût | pusse |
| vouloir | voulut | voulût | voulusse |
| dire | dit | dît | disse |
4. The Pluperfect Subjunctive
The pluperfect subjunctive (subjonctif plus-que-parfait) is the compound form of the imperfect subjunctive. It uses the imperfect subjunctive of the auxiliary (avoir or être) + past participle. It replaced the past subjunctive in the strict tense sequence after a past main verb.
qu'il eût fait (that he had done): pluperfect subjunctive of faire
qu'elle fût venue (that she had come): pluperfect subjunctive of venir
Formal / literary: Il était content qu'elle fût venue. (pluperfect subjunctive)
Modern: Je doutais qu'il ait compris.
Formal: Je doutais qu'il eût compris.
5. The Pluperfect Subjunctive as Conditional Perfect
There is a particularly important literary use of the pluperfect subjunctive: in formal and classical French, it can replace the conditional perfect (conditionnel passé) in the result clause of a conditional sentence. This use is strictly confined to literary and very formal registers.
Standard French (conditional perfect)
Si tu l'avais su, tu aurais agi différemment.(If you had known, you would have acted differently.)
Literary / formal (pluperfect subjunctive)
Si tu l'avais su, tu eusses agi différemment.(If you had known, you would have acted differently.)
(Without that encounter, he would never have understood the truth.)
Elle eût préféré se taire.
(She would have preferred to remain silent.)
6. Reading Examples from Literary Texts
The following examples are constructed in the style of nineteenth-century French prose, illustrating the forms as they appear in context.
Il exigeait qu'elle restât silencieuse.
(He required that she remain silent.): modern: qu'elle reste
Elle craignait que son fils ne tombât malade.
(She feared that her son might fall ill.): modern: qu'il tombe
Le ministre ordonna qu'on procédât immédiatement.
(The minister ordered that they proceed immediately.): modern: qu'on procède
Il eût voulu partir, mais les circonstances l'en empêchaient.
(He would have liked to leave, but circumstances prevented him.)
Jamais elle n'eût cru que cela fût possible.
(She would never have believed that was possible.)
7. Recognising the Forms: A Practical Guide
When reading a French literary text and encountering an unfamiliar form, the following patterns signal an imperfect or pluperfect subjunctive:
| What you see | What it likely is | Clue |
|---|---|---|
| parlât, allât, donnât | Imperfect subj. of -er verb (3rd sg.) | Circumflex + -ât ending |
| finît, partît, sortît | Imperfect subj. of -ir verb (3rd sg.) | Circumflex + -ît ending |
| prît, dît, fît, vît | Imperfect subj. of -re/-ir verb (3rd sg.) | Circumflex on monosyllable |
| fût, eût | Imperfect subj. of être / avoir | Circumflex distinguishes from fut, eut (passé simple) |
| parlasse, parlasses | Imperfect subj. of -er verb (1st/2nd sg.) | Double -ss- after the stem vowel |
| eût fait, fût venu | Pluperfect subjunctive | eût / fût + past participle |
| eût fait (no que, no trigger) | Conditional perfect replacement | Outside a subjunctive-trigger context |
il fut (passé simple of être) vs. il fût (imperfect subjunctive of être)
il eut (passé simple of avoir) vs. il eût (imperfect subjunctive of avoir)
il fit (passé simple of faire) vs. il fît (imperfect subjunctive of faire)
In critical editions of literary texts, this distinction is always preserved in print.
8. Modern Survivals
A handful of imperfect subjunctive forms survive in fixed expressions and set phrases in modern French, sometimes without speakers realising their grammatical origin.
| Expression | Analysis | Modern equivalent / meaning |
|---|---|---|
| Dieu soit loué | Present subj. (not imperfect) (but often confused) | God be praised |
| à Dieu ne plaise | Present subj. of plaire | God forbid |
| fût-ce | Imperfect subj. of être (concessive) | even if it were / even if only |
| ne fût-ce que | Imperfect subj. (concessive) | if only / even if only |
| eût-il su | Pluperfect subj. (conditional inversion) | Had he known... (= s'il avait su) |
| quand bien même il eût voulu | Pluperfect subj. | Even if he had wanted to |
Il faudrait une réforme profonde, fût-ce au prix de tensions sociales.
(A profound reform would be needed, even if it came at the cost of social tensions.)
9. Register Summary
| Register | Imperfect subjunctive used? | Notes |
|---|---|---|
| Everyday spoken French | Never | Would sound absurd and comically pedantic |
| Informal written French | Never | Not appropriate in emails, messages, informal essays |
| Standard DELF/DALF writing | Not expected | Present subjunctive always correct |
| Formal academic / administrative | Occasionally, in very elevated style | fût-ce, ne fût-ce que acceptable |
| Literary texts (19th-20th century) | Regularly | C1 reading comprehension requires recognition |
| Classical literature / theatre | Systematically | Racine, Corneille, Molière, Voltaire use it throughout |
Lesson Summary
- The imperfect subjunctive has virtually disappeared from spoken and informal written French. At C1, the goal is recognition, not production.
- It replaced the present subjunctive after a past or conditional main verb, in the strict classical tense sequence.
- Formation: 3rd person singular passé simple stem + endings -sse, -sses, -ˆt, -ssions, -ssiez, -ssent. The circumflex on the 3rd singular is the most visible marker.
- Key irregulars: fût (être), eût (avoir), fît (faire), vît (voir), vînt (venir), pût (pouvoir).
- The pluperfect subjunctive = imperfect subjunctive of avoir/être + past participle. It replaced the past subjunctive after a past main verb.
- The pluperfect subjunctive also functions as a literary conditional perfect in the result clause of conditional sentences: il eût voulu = he would have liked.
- Reading key: circumflex accent distinguishes imperfect subjunctive from passé simple (il fût vs. il fut).
- Modern survivals: fût-ce, ne fût-ce que (even if only) appear in contemporary formal writing and journalism.
- In -ir verbs, the imperfect subjunctive looks identical to the present subjunctive except for the circumflex on the 3rd singular (qu'il finît vs. qu'il finisse).
