How do we use the past perfect?
The past perfect is used if there are two past actions. Both of these actions have finished, but one of the actions occurred first. We can simply use the past simple and give the time, for instance: I got up at 7 o´clock and I had breakfast at 8 o´clock. However, we usually use the past perfect to state that the first action finished first, I had already got up and then I ate my breakfast.
Form and word order: SUBJECT + HAD + PAST PARTICIPLE
