Common everyday usage patterns

Sequencing of past events

The plus-que-parfait is used to express a past action that happened before another past action. For example, “J’avais mangé avant qu’il ne soit arrivé” (I had eaten before he arrived).

Background information

It is also used to provide background information or set the stage for a main past event. For instance, “Quand je suis arrivé, ils avaient déjà fini de manger” (When I arrived, they had already finished eating).

Hypothetical or reported speech

In indirect speech, the plus-que-parfait is used to report what someone had said or thought in the past. For example, “Il avait dit qu’il viendrait demain” (He had said that he would come tomorrow).

Interactions with other tenses

– The plus-que-parfait is often used in conjunction with the passé composé (simple past) to establish the sequence of past events. The passé composé describes the more recent action, while the plus-que-parfait describes the action that occurred earlier.
– It can also be used with the conditional mood to express a hypothetical past event, like “Si j’avais su, j’aurais agi différemment” (If I had known, I would have acted differently).
– When used in reported speech, it can be combined with the conditional mood or the imperfect subjunctive to reflect the original mood and tense of the reported statement.

Summary

The French plus-que-parfait tense is an essential part of the language for expressing past actions that occurred before other past actions, providing background information, and reporting past statements or thoughts. It is an integral component of constructing complex and accurate narratives in French.
