What this grammar point covers
The past perfect is a tense used to talk about an action that happened before another action in the past.
When to use it
Use the past perfect when you want to show that one action happened before another past action or time.
Key forms
- had + past participle (e.g. had eaten, had gone, had finished)
Examples
They had finished dinner when the movie started.
I had never seen that film before.
We had already done our homework.
Tips
- Always use 'had' with all subjects (I, you, he, she, it, we, they).
- Do not use 'had' twice (e.g. not 'had had went', but 'had gone').
- The past perfect is often used with words like 'before', 'after', 'already', or 'when'.
Exceptions and edge cases
- Some verbs have irregular past participles (e.g. 'go' → 'gone', 'see' → 'seen').
