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.
The team had won before I arrived.
My sister had just left when we walked in the door.
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.
The team had won.
My sister had just left.
