Form — had + past participle
| example | |
|---|---|
| positive | I had already seen the film. · She had met him before. |
| negative | I hadn't seen it before. · They hadn't finished the job. |
| question | Had you seen the film? · Where had he met her before? |
Regular past participles end in -ed (finished, lived). Irregular ones must be memorised (seen, met, gone, been, done, written, taken, given, broken, drunk).
The order of past actions
The past perfect shows that one past action happened before another past action:
Before I finally found a job, I had been to about thirty interviews.
If one action happens immediately after the other, use past simple for both:
❌ When Colin had arrived at the door, Sheila opened it.
✅ When Colin arrived at the door, Sheila opened it straight away.
Useful time words and linking phrases:
earlier · before · already · never ... before · by the time · by + a time
Four years earlier, she had become the first female American pilot in space.
I'd never liked Japanese food before, but the meal was lovely.
By the time Grace decided to apply, the position had been filled.
Past perfect or past simple?
Use past simple (not past perfect):
- if the order of actions is clear from the context: I got my first job after I left university.
- if the order of actions is the same as the order of the verbs in the sentence.
Compare:
When I got to the café, everyone ordered their drinks. (= I got there first, then they ordered.)
When I got to the café, everyone had ordered their drinks. (= They ordered first; I arrived later.)
Giving reasons
Use the past perfect to give a reason, often with because:
Eileen became the commander because she had already flown as a pilot.
Emily was unhappy — her husband hadn't bought her a present.
Superlatives and the first time
Past perfect (often with ever) pairs naturally with superlative adjectives and 'the first/second/best time':
It was the worst meal I had ever eaten!
We went to Egypt in 1996. It was the first time we 'd travelled outside Europe.

Frequently Asked Questions
How do you form the past perfect simple?
Use had + past participle. Regular participles end in -ed (finished, lived). Irregular ones must be memorised (seen, met, gone, been, taken, written, broken). Negatives use hadn't, questions invert: 'Had you seen it before?'
When do you use past perfect and when past simple?
Past perfect shows that one past action happened before another past action: 'Before I found a job, I had been to 30 interviews.' Use past simple if the order of actions is already clear from the context, or if the actions happen immediately one after the other in the order written: 'When Colin arrived, Sheila opened the door' (immediate). Don't use past perfect for immediate sequences.
Why do you use past perfect with 'by the time' and 'before'?
Linking words like 'by the time', 'before', 'after', 'already', 'never ... before' and 'earlier' typically mark the action that came first as past perfect: 'By the time we arrived, the meeting had ended.' The past simple in the main clause is the later action.
Why do you use past perfect after 'It was the first time'?
The structure is 'It was the first/second/best/worst time + past perfect': 'It was the first time we had travelled outside Europe.' The same applies with superlative + ever in a past context: 'It was the worst meal I had ever eaten.' The past perfect anchors the experience as earlier than the past moment described.
