Imparfait du subjonctif – Subjunctive Imperfect (Literary)

The imparfait du subjonctif is a literary tense used to express the same ideas as the present subjunctive, but in a past time frame.
It appears almost exclusively in formal literature, historical writing, and very formal speech.
In modern spoken French, it is replaced by the present subjunctive or the plus-que-parfait du subjonctif in context.

Mood:

The subjunctive mood expresses doubt, emotion, possibility, necessity, or hypothetical situations, but here it is applied to the past.

  • Mood: Subjunctive (uncertainty, emotion, hypothetical in a past context)

Usage:

  • After verbs and expressions that require the subjunctive, when the main verb is in a past tense:
    Il fallait qu’elle vînt immédiatement.
    (It was necessary that she come immediately.)
  • In conditional or hypothetical literary sentences:
    Si j’eusse su qu’il fût là…
    (If I had known that he was there…)
  • To maintain past-time sequence in formal writing.

Formation:

Formed from the passé simple stem of the verb, plus the subjunctive imperfect endings:

  • -sse, -sses, -^t, -ssions, -ssiez, -ssent
    (^t means no extra letter, just the stem + t)
