Past Perfect (I had done / had been doing)

Expressing an action that happened before another past time or event (the "past of the past").

Core Structure & Formula

Past Perfect Simple: Subject + had + Past Participle (had left, had seen, had submitted)

Past Perfect Continuous: Subject + had been + verb-ing (had been waiting, had been researching)

AThe "Past of the Past"

When we are already talking about the past, we use the past perfect to refer to something that took place even earlier.

•When Aisha arrived at the conference, the keynote speaker had already finished.

•When we checked the lab last night, we found that somebody had left the equipment running.

•Leo didn't need to read the article again. He'd already reviewed it for his essay.

BPast Perfect Continuous for Duration before Past Event

Shows that an activity had been ongoing up to or right before another event in the past.

•At last the results were released. I'd been refreshing the page for 20 minutes.

•Tom was exhausted when he finished the shift. He'd been working hard all day.

•We'd been rehearsing our presentation for about half an hour when the projector broke.
