Literary Subjunctive Forms (Imparfait du subjonctif)

What is the imparfait du subjonctif?

The imparfait du subjonctif (imperfect subjunctive) is a past tense of the subjunctive mood used mainly in written, formal or literary French. Like the present subjunctive, it expresses non‑factual or subjective ideas (wishes, doubts, necessity, emotion, possibility), but it places that subjectivity in a past narrative or literary context. In everyday spoken French the present subjunctive usually replaces it; you will encounter the imparfait du subjonctif most often in novels, historical writing, official documents in an elevated style, or in fixed formal expressions.

When do I use the imparfait du subjonctif?

1) In literary or formal narrative after a past tense main verb

In storytelling (passé simple, imparfait) authors often use the imparfait du subjonctif in the subordinate clause. Example:
French: "Elle souhaita qu'il réussît."
English: "She wished that he would succeed."

Modern / spoken equivalent: "Elle souhaitait qu'il réussisse."

2) After conjunctions that require the subjunctive, in a past narrative
- Conjunctions like bien que, pour que, avant que, à moins que require the subjunctive. When the surrounding narration is in a past tense and the author keeps a literary tone, the imparfait du subjonctif appears.
- French: "Bien qu'il fût tard, ils restèrent."
- English: "Although it was late, they stayed."
- French: "Il parla bas pour que le bébé n'entendît pas."
- English: "He spoke quietly so that the baby would not hear."

3) In clauses after verbs of wishing, fearing, commanding, doubting when the main verb is past (literary register)
- French: "Il craignait que les témoins ne sussent la vérité."
- English: "He feared that the witnesses might know the truth."

4) Fixed literary expressions and older set phrases
- You will meet some fixed formulations in literature that use these forms; they sound formal or archaic in speech.
- French: "Quoi qu'il en fût..." ("Be that as it may...")

How is the imparfait du subjonctif formed?

Basic idea: the imparfait du subjonctif uses stems closely related to the passé simple (the literary past) and takes special endings. The written endings are generally: -sse, -sses, -^t (circumflex often on the vowel), -ssions, -ssiez, -ssent.

A practical summary you can use:
- Many regular -er verbs end up with an -ass- stem (parler -> parlasse...).
- Many -ir and -re verbs form stems with -iss- (finir -> finisse..., vendre -> vendisse...).
- Many common irregular verbs have unique stems (être -> fusse, avoir -> eusse, pouvoir -> pusse, savoir -> susse, venir -> vinsse, etc.).

Because stems come from the passé simple and some verbs are irregular, it is easiest and safest to learn the common irregulars and to memorize the pattern on a few regular verbs. Below are full conjugation examples for typical verbs (six forms: je / tu / il/elle / nous / vous / ils/elles):

Regular -er verb (parler)
- je parlasse, tu parlasses, il parlât, nous parlassions, vous parlassiez, ils parlassent
- Sentence: "Elle ordonna qu'on parlât bas." — "She ordered that people speak quietly."

Regular -ir verb (finir)
- je finisse, tu finisses, il finît, nous finissions, vous finissiez, ils finissent
- Sentence: "Il souhaitait qu'elle finît son travail avant la nuit." — "He wished she would finish her work before night."
(Modern: "Il voulait qu'elle finisse...")

Regular -re verb (vendre)
- je vendisse, tu vendisses, il vendît, nous vendissions, vous vendissiez, ils vendissent
- Sentence: "Il ordonna que la maison ne fût vendisse pas." — (slightly contrived) "He ordered that the house not be sold." (More natural: use passive/other structures.)

Examples: contrast with modern (spoken/written) French

Literary: "Il fallait qu'il fût là." — Modern: "Il fallait qu'il soit là." (Both mean: "He had to be there.")
Literary: "Bien qu'il vînt tard, il resta." — Modern: "Bien qu'il vienne tard, il reste." (If the main verb is past, a speaker will usually keep the present subjunctive: "bien qu'il vienne tard, il est resté" — but in literature you will meet "vînt".)

When to prefer the present subjunctive instead (practical advice)

In everyday speech and most informal writing, use the present subjunctive (que je parle, que tu viennes, qu'il soit) rather than the imparfait du subjonctif. The imparfait du subjonctif is optional and stylistic; it gives a literary flavor or a formal tone.

Common mistakes to avoid

Confusing registers: Don’t use the imparfait du subjonctif in normal spoken conversation; it sounds archaic or pompous.
Wrong sequence: Don’t use the imparfait du subjonctif after si for counterfactual conditions. Correct: "Si j'avais su..." (imperfect or pluperfect indicative), not "Si j'eusse su..." (archaic and generally avoided).
Mixing tenses: Learn when the subordinate action is simultaneous vs anterior. For an action anterior to a past main clause, literature uses the plus‑que‑parfait du subjonctif (e.g., "qu'il eût fini") rather than the imparfait du subjonctif.
Forgetting irregular stems: memorize the common irregular stems (fuss‑ / euss‑ / vins‑ / priss‑ / pusse‑ / etc.).

Quick reference: samples and translations

"Il fallait qu'il fût à l'heure." — "He had to be on time." (être → fût)
"Bien qu'elle fût jeune, elle commandait respect." — "Although she was young, she commanded respect." (être → fût)
"Elle désirait qu'il vînt la voir." — "She wanted him to come see her." (venir → vînt)
"Il craignit qu'on ne sût la vérité." — "He feared that the truth might become known." (savoir → sût / sussent depending on person)
"Pour que l'affaire pût réussir, il fallut des efforts." — "So that the venture could succeed, efforts were required." (pouvoir → pût)

Glossary (simple definitions)

Subjunctive (subjonctif): a mood used to express subjectivity (wishing, fearing, necessity, doubt). Not a tense.
Imparfait (imperfect): a past tense (indicative imparfait) — here the term appears in the name "imparfait du subjonctif" but the subjunctive form is a distinct literary past subjunctive.
Passé simple: the literary simple past tense; stems of the passé simple often form the basis for the imparfait du subjonctif.
Stem / radical: the part of the verb to which endings are attached.

Summary: practical takeaways

The imparfait du subjonctif is a literary/archaic past subjunctive; it’s correct and useful for reading literature and formal documents, but not necessary in everyday speech.
Formed from passé simple stems with endings like -sse / -sses / -^t / -ssions / -ssiez / -ssent; many verbs are irregular, so learn common irregular forms.
In modern spoken/written French you will usually substitute the present subjunctive; when reading literature, recognise the imparfait du subjonctif as a stylistic (often narrative) choice.
