Past Perfect Tense

Past perfect tense verbs are formed with the helping verb had and the verb's past participle. 

They show an action that came before another action in the past. 

Although this verb tense shows an action that came before another action in the past, that other action does not have to be stated in the sentence. 

It can simply be implied. 

For instance, these sentences are still made with the past perfect verb tense although the past action is not stated like it is in the sentences above.

Every verb has three perfect tenses. 

The three perfect tenses are formed with the helping verbs have, has, had, will and shall and the past participle of the verb. 

1. Present Perfect Verbs are formed with the helping verbs has and have.

2. Past Perfect Verbs are formed with the helping verb had.

3. Future Perfect Verbs are formed with the helping verbs will have and shall have.

You need to know what a past participle is because past perfect verbs are formed using a verb's past participle.
