Start with the contrast
Jo arrived at six. The talk had started at five fifty, so she missed the opening. In another version, Jo arrived at five forty and the talk started ten minutes later. The order of events changes the grammar needed to make the meaning clear.

Jo arrived at six. The talk had started at five fifty, so she missed the opening. In another version, Jo arrived at five forty and the talk started ten minutes later. The order of events changes the grammar needed to make the meaning clear.
In the first version, was the talk already in progress when Jo arrived?
Compare your idea
Yes. Had started places its beginning before her arrival.
How it works
Use past perfect, had plus a participle, to look back from a past point to an earlier event. Use past simple for the main past viewpoint or sequence.
Past perfect is not mandatory for every earlier event. Words such as before and after can already make the order clear. Use the form when the earlier completion matters or prevents a mistaken sequence.
Earlier event: had + participle. Past viewpoint: past simple.
Reference situation
The talk had started when Jo arrived.
The start was earlier than the arrival.

I couldn’t open the file because I’d forgotten the password.
An earlier event explains a past problem.
Had you met before the course began?
This asks about an event earlier than another past event.
One mistake worth avoiding
Instead of: When I arrived, they have already left.
Say: When I arrived, they had already left.
The reference point is past, so use had to look further back.
You say
Hear the prompt, answer aloud, then deliberately reveal or hear one possible model. Check it and retry with a changed detail.
Your turn 1
Give a past problem and an earlier cause.
Compare a possible model
Reveal the model text
I couldn’t call because I had lost my phone.
Check yourself: Keep the main viewpoint and earlier cause distinct.
Retry with one detail of your own. Other wording is welcome when it meets this check.
Your turn 2
Describe the opposite order using clear sequence words.
Compare a possible model
Reveal the model text
I arrived first, and the talk started later.
Check yourself: Do not add past perfect when it changes the intended order.
Retry with one detail of your own. Other wording is welcome when it meets this check.
Your turn 3
Ask about an earlier experience from a past point.
Compare a possible model
Reveal the model text
Had you visited the town before you moved there?
Check yourself: Use had before the subject.
Retry with one detail of your own. Other wording is welcome when it meets this check.
Two guided self-checks
Say or write your answer before opening a model.
Self-check 1
Two facts: The train left at five. I arrived at five ten. Join using by the time.
Compare a model and explanation
By the time I arrived, the train had left.
The departure was already complete.
Self-check 2
Expand I’d in “I’d forgotten the password.”
Compare a model and explanation
I had forgotten the password.
The participle forgotten identifies had here.
