The past perfect tense is used to indicate the past actions. When we talk about something that happened in the past, we use the past perfect tense because the action happened before another action in the past.
The past perfect tense is used in the previous action between two completed actions of the past; simple past is used in the later action. This tense is formed with the past tense form of “to have the verb” (had) + the past participle of the main verb.
