Positive: Subject + had been + verb-ing

Negative: Subject + had not (hadn’t) been + verb-ing

Use of Past Perfect Continuous Tense

The Past Perfect Continuous tense is employed in various situations, such as:

a. To express actions that started in the past and continued up to a certain point in the past.
