The past perfect continuous describes an action that was in progress up until a point in the past, often explaining the cause of a later past situation. It's the "past before the past," but with the emphasis on duration and process rather than simple completion, the same relationship the present perfect continuous has to the present perfect simple, just shifted one step further back in time.
This is the least frequently needed of the core English tenses in everyday conversation, but it appears reliably in higher-level exam writing and in more sophisticated storytelling, so it's worth understanding clearly even if you use it less often than the others.

7. Common Mistakes
❌ Incorrect
✅ Correct
Why
I had been knowing him for years before that.
I had known him for years before that.
"Know" is stative, never used in any continuous form.
She had been study all night.
She had been studying all night.
The main verb needs -ing after "been."
I was working for hours before you called. (meant as past perfect)
I had been working for hours before you called.
The earlier duration needs "had been," not just past continuous.
He has been running before the race started.
He had been running before the race started.
A past reference point ("before the race started") needs "had been," not "has been."
