The short answer
Use the past perfect for the earlier of two past actions: had + past participle. Put the later action in the simple past. For example, By the time we reached the station, the train had left.
By the time we reached the station, the train had left.
Why it works: Had left happened first. Reached happened later.

Maya had saved the document before her laptop restarted.

savedthe document before her laptop restarted. What changes: Before already makes the order clear here, so the simple past is also natural in everyday speech. -
I had never tried Thai food before I moved to Bristol.
The period of not trying Thai food came before the move to Bristol.
Not this:After I moved to Bristol, I
tried Thai food for the first time. What changes: The later action uses the simple past, while the earlier experience can use the past perfect. -
The guests had already eaten when the restaurant closed.
Already emphasizes that the guests finished eating before the restaurant closed.
Not this:The restaurant closed
after the guests ate. What changes: The order is clear from after, but already adds the useful idea that the earlier action was complete by that time. -
Had Leo checked the address before he sent the parcel?
A past perfect question asks whether checking happened before the later past action of sending.

First, find the two past moments. Ask which one happened earlier. If the listener could misunderstand the order, use had plus the past participle for that earlier event. The other event normally stays in the simple past.
Find the earlier past action
Use the past perfect when you are looking back from one past moment to an action that was already complete. The later point gives your listener a reference time, and the past perfect tells them what had happened before it.
When I opened the shop, someone had left a note on the door.
Opening the shop happened later. Leaving the note happened first.
When I opened the shop, someone left a note on the door.
This can mean the person left the note at the same time as or after the shop opened, so it gives a different timeline.
Which action came first: opening the shop or leaving the note?
Leaving the note came first, so use had left for that action.
Build the past perfect correctly
The form is had plus a past participle for all subjects. Regular verbs usually use the -ed participle, such as had worked. Irregular verbs need their special past participle, such as had gone, had seen, or had written.
They had finished the report before the meeting began.
Finished is the past participle of finish. The meeting began later.
She had written the email before lunch.
Written is the past participle of write. Do not use had wrote.
Complete the sentence: He had ____ the keys before he left. Choose found or find.
Use found. It is the past participle of find.
Make negatives and questions
Add not after had for a negative statement. In a question, move had before the subject. The main verb remains a past participle in both patterns.
We hadn't booked a table before we arrived.
Hadn't booked means the booking did not happen before the arrival.
Had you spoken to the manager before the call?
Had comes before you because this is a question about an earlier past conversation.
Turn this into a question: You had met the new neighbor before.
Had you met the new neighbor before?
Use time words as useful clues
Before, after, when, by the time, already, and never often appear with the past perfect. They can help you see the timeline, but they do not automatically require this tense. Decide first whether you need to show an earlier completed action.
By the time the teacher arrived, the students had chosen their groups.
Choosing groups was complete before the teacher arrived.
After the teacher arrived, the students chose their groups.
This describes the opposite order, so the simple past with after gives a clear result.
Choose the earlier action: By the time the bus came, we had waited for twenty minutes.
Waiting began and continued before the bus came, so had waited looks back from the bus arriving.
Know when the simple past is enough
A clear time expression can make the past perfect unnecessary. Everyday English often uses two simple-past verbs when before or after already tells the listener what happened first. Use the past perfect when it adds clarity, not as a decoration.
After Sam paid the bill, he left the café.
After gives a direct order, so paid and left can both be simple past.
Sam was relieved because he had paid the bill.
Had paid explains the earlier reason for Sam's feeling at a later past time.
Which sentence needs extra help with the order: I washed up after dinner, or I was tired because I had washed up?
The second sentence uses had washed up to explain an earlier completed action behind the later feeling.
Before you go
Remember this
Use had plus a past participle for the earlier of two past actions. Keep the later action in the simple past. Choose the past perfect when it helps your listener follow the order, and check that the word after had is a past participle.
