Past Perfect Tense
The past perfect tense is used to show that one action happened before another action or time in the past. It creates a clear sequence of past events and removes confusion about which event occurred first. This tense is especially useful in storytelling, reporting events, writing academic analysis, and describing cause-and-effect relationships in the past.
Structure
Subject + had + Past Participle (V₃)
Examples:
-
She had finished her assignment before the teacher checked it.
-
They had left by the time we arrived.
-
I had never visited Karachi before 2020.
Note: The helping verb “had” is used with all subjects (I, you, we, they, he, she, it).
When Past Perfect is Used
1. To show the earlier of two past actions
When two actions happened in the past, the past perfect shows the first action, and the simple past shows the second.
-
She had already eaten when I called her.
-
The train had departed before we reached the station.
This clarifies the order:
1st: she ate
2nd: I called
2. To show cause and effect in the past
Past perfect explains the reason behind a later past situation.
Examples:
-
He failed the exam because he had not studied.
-
She was tired because she had worked all day.
3. To talk about experiences before a point in the past
It is often used with words like never, ever, already, just, before, by the time, until then.
Examples:
-
I had never seen snow before last winter.
-
She had already completed the project by Monday.
4. Reported or indirect speech
When reporting what someone said in the past about a time even earlier.
Examples:
-
He said he had lost his wallet.
-
She told me they had moved to another city.
5. Storytelling and narration
Used to make the sequence of events clear in stories, novels, or reports.

-
When the guests reached the hall, the ceremony had started.
