The past perfect tense is used to describe an action that happened before another action in the past. It is formed by using the auxiliary verb "had" followed by the past participle of the main verb. For example:
- She had already eaten dinner when I arrived.
- They had finished their homework before going to bed.
- He had studied for the test, so he felt confident.
The past perfect is often used in combination with the simple past tense to show the sequence of events in the past.
