Question

where to use past perfect tense??

Answer 1

However we use past perfect to talk about something that happened before another action in the past, which is usually expressed by the past simple. For example: "I had already eaten my dinner when he called."

Answer 2

When we talk about something that happened in the past we sometimes want to refer back to something that happened before that time. We can use the past perfect tense (had + past participle) to do this. mark me as brainliest
