How to Form the Past Perfect
The Past Perfect is formed with had + the past participle of the main verb. The same form is used for all subjects — there is no variation for I, he, she, we, or they. Had never changes.
All subjects: subject + had + past participle
I / You / He / She / We / They + had + past participle
I had finished. · She had left. · They had arrived. · We had eaten.
Regular verbs — past participle = past simple (-ed form)
finish → finished · arrive → arrived · walk → walked · study → studied
She had finished the report. · They had arrived before us.
Irregular verbs — past participle must be memorised
Many common verbs have irregular past participles. These are the same participles used with the Present Perfect (have + past participle). If you know the Present Perfect, you already know the Past Perfect participle.
go → gone
come → come
see → seen
do → done
eat → eaten
write → written
take → taken
give → given
speak → spoken
know → known
buy → bought
build → built
make → made
leave → left
meet → met
forget → forgotten

The logic of time — why the Past Perfect exists
The Past Perfect solves a specific problem in English: how do you talk about two events in the past when one happened before the other? The Past Simple describes what happened. The Past Perfect describes what had already happened before that.
Two actions in the past — the Past Perfect is further back in time:
She had left (Past Perfect)
→
I arrived (Past Simple)
→
NOW
The Past Perfect always describes the earlier of two past events.
