The subjonctif imparfait is the rarefied air of French grammar. Nobody speaks it; almost nobody writes it any more outside specific genres. Yet it is everywhere in classical French literature — Hugo, Flaubert, Balzac, Stendhal, Voltaire, Madame de La Fayette — and it survives in the very highest registers of contemporary French: presidential speeches, legal codes, the Académie française's discussions, certain editorial columns of Le Monde. To read a nineteenth-century novel competently you have to recognize qu'il vînt, qu'elle fût, qu'ils eussent compris. To write at the highest formal registers — and that is what C2 grammatically aspires to — you may even, on rare occasions, deploy it yourself.
This page presents three annotated passages, explains the form, and trains the recognition skills. The forms are presented as recognition-only for almost all C2 learners; production is a fine art reserved for those who write professionally in formal French.
What it is, briefly
French has four tenses in the subjunctive mood:
| Tense | Use | Status |
|---|---|---|
| Subjonctif présent (qu'il vienne) | active, productive | universal in modern French |
| Subjonctif passé (qu'il soit venu) | active, productive | universal in modern French |
| Subjonctif imparfait (qu'il vînt) | classical sequence-of-tenses | literary only |
| Subjonctif plus-que-parfait (qu'il fût venu) | classical sequence-of-tenses | literary only |
The two literary tenses are triggered by the same things as the present subjunctive (il faut que, bien que, avant que, etc.) — but only when the main verb is in a past tense and the writer is committed to formal classical French. The traditional rule of concordance des temps required that a main verb in the past triggered an imparfait or plus-que-parfait subjunctive in the subordinate clause:
| Main clause | Old (literary) | Modern |
|---|---|---|
| Il fallait (impf) que… | qu'il vînt | qu'il vienne |
| Bien que (with past main verb) | cela fût | cela soit |
| Il craignait (impf) que… | qu'elle ne partît | qu'elle ne parte |
| Il avait fallu (pqp) que… | qu'il fût venu | qu'il soit venu |
In modern French, the rule is largely abandoned: the subjonctif présent now does the work of the imparfait, and the subjonctif passé does the work of the plus-que-parfait. The literary forms survive only in deliberately formal or classical writing.
Sample 1: Hugo, Les Misérables
Il fallait qu'il vînt. Quelque chose, plus puissant que sa volonté, l'attirait vers cette maison. Bien que la nuit fût profonde et que la pluie tombât sans relâche, il se mit en route.
— adapted from Victor Hugo, in the Hugolian register
Three subjonctif imparfait forms in three sentences: vînt, fût, tombât. Take them in turn.
Vînt (venir, 3sg subj. impf.)
Il fallait qu'il vînt.
It was necessary that he come. (Literary; modern: 'qu'il vienne'.)
The form vînt is the third-person singular subjonctif imparfait of venir. It is built from the passé simple stem of the verb. The passé simple of venir in 3sg is il vint — and the subjonctif imparfait adds a circumflex to the stressed vowel: vînt.
This is the central morphological pattern: subjonctif imparfait 3sg = passé simple 3sg + circumflex. The circumflex on the third-singular is the diagnostic. Without it, you have a passé simple; with it, you have a subjonctif imparfait.
| Verb | Passé simple 3sg | Subjonctif imparfait 3sg |
|---|---|---|
| venir | il vint | qu'il vînt |
| voir | il vit | qu'il vît |
| être | il fut | qu'il fût |
| avoir | il eut | qu'il eût |
| faire | il fit | qu'il fît |
| dire | il dit | qu'il dît |
| pouvoir | il put | qu'il pût |
| savoir | il sut | qu'il sût |
| tenir | il tint | qu'il tînt |
The pair vint / vînt is the canonical illustration: same letters, different mood. Without the circumflex, it is the indicative passé simple; with it, the subjunctive imparfait.
Fût (être, 3sg subj. impf.)
Bien que la nuit fût profonde…
Although the night was deep… (Literary; modern: 'soit profonde'.)
Fût is the third-singular subjonctif imparfait of être. The passé simple of être is il fut (no circumflex); the subjonctif imparfait is qu'il fût (with circumflex). The two forms differ by a single mark on the u.
The trigger here is bien que, which always takes the subjunctive. With a past main verb (il se mit en route — passé simple), classical sequence-of-tenses calls for the imparfait subjunctive in the subordinate clause. Modern French would say:
Bien que la nuit soit profonde, il se mit en route.
Although the night was deep, he set off. (Modern blend: passé simple narrative + present subjunctive.)
This blend is what most modern formal writing actually does — passé simple is preserved for the narrative, but the subjunctive is shifted to présent.
Tombât (tomber, 3sg subj. impf.)
…et que la pluie tombât sans relâche.
…and that the rain was falling without letup. (Literary; modern: 'tombe sans relâche'.)
Tombât is the third-singular subjonctif imparfait of tomber. Tomber is a regular -er verb, with passé simple il tomba; the imparfait subjunctive adds a circumflex on the a: qu'il tombât. The pattern is universal across -er verbs:
| -er verb | Passé simple 3sg | Subjonctif imparfait 3sg |
|---|---|---|
| parler | il parla | qu'il parlât |
| aimer | il aima | qu'il aimât |
| chanter | il chanta | qu'il chantât |
| penser | il pensa | qu'il pensât |
These -ât forms in third-singular are extremely distinctive — once your eye is trained, you spot them at fifty paces.
Sample 2: Flaubert-style portrait
Il craignait qu'elle ne partît avant son retour. Pendant des heures il imaginait toutes les phrases qu'il lui dirait, toutes les explications qu'il faudrait qu'il donnât pour qu'elle restât.
Two new subjonctif imparfait forms here: partît and donnât, plus a third (restât) at the end. Note also the ne explétif in qu'elle ne partît — a literary trace that reinforces the formal register.
Partît (partir, 3sg subj. impf.)
Il craignait qu'elle ne partît avant son retour.
He feared that she might leave before his return. (Literary; modern: 'qu'elle parte'.)
Partir in passé simple 3sg is elle partit; the subjunctive imparfait adds a circumflex on the i: qu'elle partît. The trigger is craindre que, which takes the subjunctive; with the main verb in imparfait (il craignait), classical concordance calls for the imparfait subjunctive in the subordinate.
The ne explétif (qu'elle *ne partît) is a redundant *ne that appears in subjunctive subordinates after verbs of fear, doubt, prevention, comparison, and after certain conjunctions (avant que, à moins que). It does not negate; it is a formal remnant. Modern French keeps the ne explétif in formal writing but drops it freely in speech.
Donnât (donner, 3sg subj. impf.) and restât (rester, 3sg subj. impf.)
…toutes les explications qu'il faudrait qu'il donnât pour qu'elle restât.
…all the explanations that it would be necessary for him to give so that she would stay. (Literary; modern: 'qu'il donne… qu'elle reste'.)
Two more -er verbs in -ât: donnât (donner) and restât (rester). The trigger for donnât is il faudrait que; for restât, the conjunction pour que. Both are textbook subjunctive triggers, and in classical French both take imparfait subjunctive when the main verb is past or conditional.
The whole sentence stacked with -ait and -ât forms — craignait, imaginait, dirait, faudrait, donnât, restât — is a paradigm of nineteenth-century literary cadence. Read aloud, the rhythm depends on these vowel endings.
Sample 3: Plus-que-parfait du subjonctif
The subjonctif plus-que-parfait is built from the subjonctif imparfait of avoir or être + the past participle. The forms of avoir and être you need:
| Auxiliary | Subjonctif imparfait |
|---|---|
| avoir | que j'eusse, qu'il eût, que nous eussions, qu'ils eussent |
| être | que je fusse, qu'il fût, que nous fussions, qu'ils fussent |
Bien qu'il eût travaillé toute la nuit, il échouait à trouver la solution. Il aurait suffi qu'on lui en eût parlé une fois pour qu'il comprît tout.
Two plus-que-parfait subjunctive forms: eût travaillé and eût parlé. Plus a simple subjonctif imparfait at the end: comprît.
Eût travaillé (avoir + travaillé, subj. plus-que-parfait)
Bien qu'il eût travaillé toute la nuit, il échouait à trouver la solution.
Although he had worked all night, he was failing to find the solution. (Literary; modern: 'bien qu'il ait travaillé'.)
The form eût is the third-singular subjonctif imparfait of avoir; combined with the participle travaillé, it forms the plus-que-parfait subjunctive — anteriority in a past subjunctive context. The trigger is bien que (always subjunctive); the main verb échouait is in imparfait, so classical concordance calls for the plus-que-parfait subjunctive to mark anteriority. Modern French uses the subjonctif passé:
Bien qu'il ait travaillé toute la nuit, il échouait à trouver la solution.
Although he had worked all night, he was failing to find the solution. (Modern.)
Eût parlé (avoir + parlé, subj. plus-que-parfait)
Il aurait suffi qu'on lui en eût parlé une fois pour qu'il comprît tout.
It would have sufficed for someone to have spoken to him about it once for him to understand everything. (Literary; modern: 'qu'on lui en ait parlé… qu'il comprenne'.)
A nest of subjunctives: eût parlé (plus-que-parfait subj.) and comprît (imparfait subj. of comprendre). The conditional past in the main clause (il aurait suffi) and the conjunction pour que both demand the subjunctive; in classical French the past conditional triggers the plus-que-parfait subjunctive in one subordinate and the imparfait subjunctive in the other.
The form comprît is the third-singular subjonctif imparfait of comprendre (passé simple il comprit → subj. imparfait qu'il comprît).
Where you encounter these forms
| Genre | Frequency |
|---|---|
| Pre-1950 literature | very high — every chapter |
| Post-1950 literary fiction | rare but not extinct (Yourcenar, Echenoz, Quignard) |
| Presidential speeches | occasional — for solemnity |
| Legal codes and decrees | preserved in some traditional formulations |
| Academic essays in humanities | occasional |
| Newspapers | almost never |
| Conversation | never |
A C2 learner is expected to recognize all major forms in classical literature without difficulty and to identify the trigger that produced them.
Production: when (if ever) to use them
Most C2 candidates will never need to produce the subjonctif imparfait or plus-que-parfait. The cases where production might be appropriate:
- Writing pastiche or historical fiction in nineteenth-century style.
- Drafting solemn formal prose — speeches, ceremonial texts, certain academic registers.
- Translation work preserving the register of a classical source.
- Literary criticism quoting and commenting on classical texts.
In any other context — modern fiction, journalism, business writing, conversation — using subjonctif imparfait will sound either antiquated or pretentious. The Académie itself has long accepted subjonctif présent in past contexts as standard usage.
Recognition table for the most frequent forms
The following table covers about 95% of the subjonctif imparfait forms you will meet in literature. All forms are third-person singular (the form most often encountered).
| Verb | Subj. impf. 3sg | Trigger example |
|---|---|---|
| être | qu'il fût | bien que cela fût vrai |
| avoir | qu'il eût | il fallait qu'il eût raison |
| aller | qu'il allât | avant qu'il s'en allât |
| venir | qu'il vînt | il fallait qu'il vînt |
| voir | qu'il vît | il craignait qu'il ne vît |
| dire | qu'il dît | bien qu'il dît la vérité |
| faire | qu'il fît | quoiqu'il fît tout son possible |
| pouvoir | qu'il pût | il aurait fallu qu'il pût |
| savoir | qu'il sût | bien qu'il le sût |
| vouloir | qu'il voulût | quoique je voulusse |
| devoir | qu'il dût | bien qu'il dût partir |
| prendre | qu'il prît | avant qu'il prît la fuite |
| mettre | qu'il mît | il importait qu'il le mît |
| comprendre | qu'il comprît | pour qu'il comprît |
| rendre | qu'il rendît | il fallait qu'il rendît |
| partir | qu'il partît | il craignait qu'elle ne partît |
| sortir | qu'il sortît | bien qu'il sortît tard |
| écrire | qu'il écrivît | il aurait fallu qu'il écrivît |
| recevoir | qu'il reçût | avant qu'il reçût la lettre |
| tenir | qu'il tînt | bien qu'il le tînt secret |
Memorize the -ât, -ît, -ût, -înt endings — they are the universal third-singular markers of the subjonctif imparfait, all distinguished from the passé simple by the circumflex.
Common mistakes
❌ Confusing 'il vint' (passé simple, indicative) with 'qu'il vînt' (subjonctif imparfait).
The two differ only in the circumflex on the *i*; in fast reading the contrast is easy to miss.
✅ 'Il vint' = he came (PS); 'qu'il vînt' = that he come (subj. impf.).
The circumflex on third-singular is the diagnostic for the literary subjunctive; without it you have the indicative passé simple.
This is the single most important recognition contrast for the C2 reader. Train your eye on circumflex vs. no circumflex in third-singular forms.
❌ Producing subjonctif imparfait in modern conversation: '*Il fallait que je vinsse.'
Sounds parodic; modern French uses 'que je vienne'.
✅ 'Il fallait que je vienne.'
(Modern usage.) It was necessary that I come.
The Académie française accepts subjonctif présent in past contexts; producing the literary forms in everyday writing or speech is overkill.
❌ Translating subjonctif imparfait as English subjunctive past ('that he were', 'that he came').
English has no living subjunctive imparfait; the natural translation is the same as for subjonctif présent.
✅ 'Bien que cela fût vrai' = 'Although that was true' (English indicative).
The literary French subjunctive in past contexts maps to the English indicative — English has lost the contrast.
Don't twist English to mirror French morphology; use natural English equivalents.
❌ Confusing the auxiliary 'eût' (subj. impf. of avoir) with 'eut' (passé simple of avoir).
*Il eut* = he had (PS); *qu'il eût* = that he have (subj. impf.). Same circumflex distinction as for *vint/vînt*.
✅ 'Il eut faim' (PS) vs 'Bien qu'il eût faim' (subj. impf.). The circumflex is the marker.
The pair *eut/eût* is one of the most common confusion pairs in nineteenth-century texts.
The circumflex on eût is the diagnostic of the subjunctive; without it, the form is passé simple of avoir. Same for fut/fût.
❌ Forgetting that the conditionnel passé deuxième forme exists: 'S'il l'eût su, il fût venu' = main-clause use of subjunctive plus-que-parfait.
In the highest literary register, the plus-que-parfait subjunctive can replace the past conditional in BOTH clauses of a hypothetical.
✅ 'S'il l'eût su, il fût venu' = 'If he had known it, he would have come' (literary equivalent of 'S'il l'avait su, il serait venu').
The conditionnel passé deuxième forme is a stylistic option in extreme formal writing; recognize it.
This rare construction — using fût venu to mean serait venu — is found in Hugo, Chateaubriand, and other very classical writers. It is recognition only for nearly all C2 readers.
