Past Perfect
had + past participle for the earlier of two past actions.
The Past Perfect tense is used to show that one action happened before another action in the past. It is formed with had + the past participle of the main verb (e.g., had eaten, had finished, had gone). We use it to make the sequence of events clear — the Past Perfect describes the earlier event, while the Past Simple describes the later event. Common signal words that appear with the Past Perfect include: already, just, before, after, by the time, when, and by + a time expression. Note that when 'before' or 'after' already makes the order obvious, you may find Past Simple used for both actions in informal speech — but in written and exam English, the Past Perfect is expected for the earlier event. For example: By the time we arrived at the cinema, the film had already started — 'had started' happened first; 'arrived' happened second.
