Past perfect
The past perfect looks back from a point in the past. Use it to show that an action was already complete, or a state already existed, before another past event or reference point.
START WITH A MOMENT
You reach the station and discover why the platform is empty.
The train had left when I arrived.First the train left. Then you arrived. The earlier event explains the later situation.
PUT IT TOGETHER

| Negative | subject + had not + past participleI had not seen the message. |
| Question | Had + subject + past participle?Had you met before the course? |
KNOW WHEN TO USE IT
Here is where it fits.
01Make the order clear
The past perfect is especially helpful when the sentence mentions the later event first, or when the order could otherwise be unclear. The past reference point can be supplied by an earlier sentence.
I could not enter the building. I had left my pass at home.
02Experience before a past moment
Look at an earlier version of yourself. What experience had you accumulated by then? The past perfect lets you discuss experience up to a past date, instead of up to the present.
Before that trip, I had never travelled alone.
03Before does not always require had
If before or after already makes the order clear, two past-simple clauses can be enough. Do not put every verb in a past story into the past perfect. Establish the earlier time, then return to the main narrative when appropriate.
I checked the address before I left.
04Completed action or ongoing process?
Use had finished to emphasize a completed result before the past reference point. Use had been working when the time spent on an activity is more important. With state verbs, the simple perfect is normally the natural choice.
SMALL CHANGES, CLEARER ENGLISH
A few things to watch.
Had needs a past participle: gone, not went.
A straightforward sequence does not need past perfect for every event.
