How do we make the Past Perfect Tense?
The structure of the Past Perfect tense is:
|subject||+||auxiliary have||+||main verb|
|conjugated in Past Simple|
The auxilary verb (have) is conjugated in the Past Simple: had
The main verb is invariable in past participle form: -ed (or irregular)
For negative sentences we insert not between the auxiliary verb and the main verb.
For question sentences, we exchange the subject and the auxiliary verb.
Look at these example sentences with the Past Perfect tense:
|subject||auxiliary verb||main verb|
Contraction with Past Perfect
When we use the Past Perfect in speaking, we often contract the subject and the auxiliary verb. We also sometimes do this in informal writing:
- I'd eaten already.
- They'd gone home.
In negative sentences, we may contract the auxiliary verb and "not":
- I hadn't finished my meal.
- Anthony hadn't had a day off for months.
- We had, OR
- We would
- We had arrived (past participle)
- We would arrive (base)
