Time Expressions in the Past Perfect Simple
The time expressions already, for, since, and yet may be used in the past perfect simple, as they are in the present perfect simple. Remember the following rules for using other time expressions:
Use after, as soon as, the moment that, until before using the past perfect simple.
Ex: After she had moved out, I found her notes./ I didn’t say anything until she had finished talking.
Use before, when, by the time before the past simple:
Ex. Before I knew it, she had run out the door. / By the time he phoned her, she had found someone new.

The past perfect simple is used to describe one action that happened before another action in the past.
In many cases a complete sentence is written in two parts with two different tenses:
The past perfect simple, to refer to the action that happened first or earlier
The past simple to refer to the action that happened second or later
Sometimes the past perfect simple is used on its own and the action that took place afterwards is understood.
After Sofie had finished her work, she went to lunch.
(First she finished her work and then she went to eat lunch.)
I washed the floor when the painter had gone.
(First the painter left and then I washed the floor.)
Harold had known about it for a while.
(First he knew about it, then others knew about it)
The past perfect simple tense is formed by using the auxiliary verb had together with the V3 (past participle). The V3 (past participle) form of a regular verb looks just like a regular verb in the past simple:
walk > walked / study > studied / stop > stopped / create > created
There are quite a few irregular verbs in English though. It pays to memorize them.
Subject had +Verb(V3)
(Past Participle) Rest of Sentence
I / You / We / They
He / She / It had met him before he became famous
had lived here for three years by the time we met
Note: The order of phrases may be switched, but the meaning will stay the same.
By the time Doris got to the party, everyone had gone home.
Everyone had gone home by the time Doris had got to the party.
Note: Had Had – A verb combination that often causes confusion in the past perfect simple is had had. Ex. I had had enough to eat but I wanted dessert anyway. The first had is the auxiliary (or helping) verb and the second had is the V3 (or past participle) of the main verb to have. It means that even though I ate enough, I wanted dessert after that. It may look strange, but it is correct.
Contractions in the Past Perfect Simple
Punctuation Tip
When you begin a sentence with a time expression, put a comma (,) after the first part of the sentence.
We often contract the subject (the person or thing that had done the action) and had:
I had > I’d – After I’d used the phone, I paid the bill.
He had > He’d / She has > She’d / It has > It’d – It’d happened so quickly, I didn’t notice.
We had > We’d / You have > You’d /They are > They’d – We’d just gotten home, when we heard the blast outside.
Negative Sentences in the Past Perfect Simple Tense
When creating negative sentences, we use the auxiliary verbs hadn’t (had not) together with the V3 (past participle) form of the verb. You can also create a negative sentence by using the auxiliary verb had with the time expression never and then the V3.
Subject Auxillery Verb Verb in V3
(Past Participle) Rest of Sentence
I / You / We / They
He / She / It hadn’t (had not) driven a car before then
had never driven a car before then
I had not eaten at that restaurant before today.
Samantha hadn’t had time to explain her side of the story.
My friends hadn’t ever gone to France.
My friends had never gone to the USA either.
Yes/No Questions in the Past Perfect Simple
To create a question that will be answered with a yes or no, start the question with Had (Hadn’t for a negative question) then add a subject (the person or thing that had done the action) followed by the V3 (Past Participle) form of the verb and only then add the rest of the sentence.
Auxiliary Verb Subject Verb in V3
(Past Participle) Rest of Sentence
Had I / you / we / they
he / she / it had time to rehearse you’re the song
Had he / she / it eaten there before
Had you cleaned up the mess by the time they came home?
Had Adam ever spoken to the CEO before he was fired?
Wh-Questions in the Past Perfect Simple
Wh- questions are questions that require more information in their answers. Typical wh- words are what, where, when, why, who, how, how many, how much.
To create a wh-question, start with the wh-word, then add had, then the subject (a person or thing that had done the action), followed by the V3 (Past Participle) form of the verb and only then add the rest of the sentence.
