Lesson 3 · Past Perfect Continuous

had been writing vs had written

Continuous or simple

had been -ing talks about an activity that went on for some time — the duration matters, not the outcome. had + V3 talks about a finished action — the result or the amount matters. And state verbs (know, believe, own) usually aren't used in the continuous.

activity or result

  • in progressI had been writing emails all day — the duration matters, not how many
  • resultI had written five emails — the outcome matters: how many, what was done
  • stateI had known him for years — know isn't used in the continuous, even with a period of time

I had been writing emails all morning when the power went off.

By noon, I had written five emails.

I had known him for years before we became friends.

She had wanted to visit Japan long before she finally went.

Where people usually slip

Not *had been knowing*, *had been believing* — state verbs usually aren't used in the continuous: I had known him for years, not *had been knowing him for years*.

Compare ordinary action verbs, where both forms are possible: had been writing / had written.

In short

  • had been -ingthe activity, duration
  • had + V3the result, amount
  • know/believeusually only had + V3
