The past perfect tense is formed with the past tense of the auxiliary verb have, which is had and the past participle of a main verb (e.g. eaten, stolen, taken). The past perfect tense in a sentence or conversation describes an event that happened in the past before another event in the simple past tense was completed in the past.
The Past Perfect Tense is used:
for an action which took place and completed in the past.
- He had hurt his back in an accident at his workplace.
- Bob had borrowed money from the bank.
- We were glad that the train had arrived on time.
for an action which happened before a definite time in the past.
- They had said their prayers by ten o'clock.
- We had cleaned up the whole place in one hour after the dinner party ended.
to show an action happened in the past before another action took place.
The event in the past perfect tense occurred before the event in the simple past tense. The words usually used here are when and after.
- They had already finished their dinner when I arrived to join them.
- When he had done his homework, he went for a walk in the park.
- After I had eaten five apples, I felt ill.
- We arrived at the cinema after the film had started.
- He had felt the same after the second rollercoaster ride.
- She had been very angry with him since he left her.
Two actions completed in the past.
When two actions were completed in the past, a past perfect tense is used to clarify which event happened earlier.
- The museum occupied the building where the art gallery was.
(The use of two simple past tenses [occupied, was] implies the museum and the art gallery occupied the same building at the same time.)
- The museum occupied the building where the art gallery had been.
(The use of the past perfect tense [had been] shows the art gallery occupied the building before it was occupied by the museum.)
Past perfect tense and some adverbs.
Words such as already, almost, just and as soon as are also used with the Past Perfect tense.
- I had already bought an umbrella when it stopped raining.
- The guests had almost finished the food by the time we reached there..
- His whole house had just burnt down when the firefighters arrived.
- As soon as she had got married, she regretted it.
Before and after
An event expressed in the past perfect tense occurs earlier than an event in the past simple tense. However, when before or after is used in a sentence, the past perfect tense becomes unnecessary as the two words - before and after – already clarify which action takes place first. The simple past tense can be used instead in both events. Changing the past perfect tense to past simple tense does not affect the meaning of the sentence. The following examples show that the meanings of the two sentences remain the same.
- After she had read the letter, she tore it into pieces.
- After she read the letter, she tore it into pieces.
- We had left the stadium before the match ended.
- We left the stadium before the match ended.
Past perfect tense used after if, if only and wish.
The past perfect tense is used in a conditional clause beginning with if, after if only or wish to express a situation in the past, especially one that did not happen in the past and is impossible to happen now.
- If you had studied hard, you wouldn't have been a janitor now.
- I would have bought two if I had brought enough money with me.
- If only he had shut up at the meeting, no one would have known his ignorance.
- If only she had listened to her mother, she wouldn't have made that wrong decision.

Past perfect tense used after certain expressions.
Past perfect tense is often used after the following expressions:
- I knew (that) his brother had gone to work overseas.
- I didn't know (that) he had become a monk.
- I thought (that) we had got on the wrong train.

Past perfect tense and the simple past tense.
The past perfect tense and the simple past tense can be used separately in different sentences. Whether the past perfect tense precedes or follows the simple past tense, the action expressed in the past perfect tense will always happen first.
- This morning we visited John in the hospital. He had been admitted with stomach pains.
- We had invited him over for a game of cards. But he wanted to go to bed.
Tenses in one clause and following clause must be the same.
The tense used in one clause must be the same as that used in the following clause; that is, simple present tense is followed by present perfect tense; and simple past tense followed by past perfect tense.

- My salad bowl was empty. Someone had eaten the salad.
