Question

why and how the past perfect is used​

Answer 1

Answer:

The past perfect refers to a time earlier than before now. It is used to make it clear that one event happened before another in the past. It does not matter which event is mentioned first - the tense makes it clear which one happened first.

Answer 2

Explanation:

We can use the past perfect to show the order of two past events. The past perfect shows the earlier action and the past simple shows the later action. Note that if there's only a single event, we don't use the past perfect, even if it happened a long time ago.
