Common mistakes
Wrong
By the time Lisa called, Mark left.
Correct
By the time Lisa called, Mark had left.
The leaving happened first, so Past Perfect marks the earlier past action.
Wrong
When Tom arrived, Anna left already.
Correct
When Tom arrived, Anna had already left.
Use had + past participle to show Anna left before Tom arrived.
Wrong
She didn't finished the email before lunch.
Correct
She hadn't finished the email before lunch.
Past Perfect negatives use hadn't + past participle, not didn't + finished.
Wrong
They had went home before midnight.
Correct
They had gone home before midnight.
After had, use the past participle. The participle of go is gone, not went.
Wrong
You finished the work before noon?
Correct
Had you finished the work before noon?
Yes/no questions in Past Perfect start with Had.
Common misconceptions
❝ I can use Past Perfect only if both past actions are written in the sentence. ❞
You can also use it with a clear past time point or past result: By Friday, Maria had finished the report.
❝ I need different forms of had for different subjects. ❞
Past Perfect uses had for all subjects: I had, she had, they had.
