Tenses Questions Medium
We use the past perfect continuous tense to describe an action that started in the past, continued for a period of time, and was still ongoing before another past action or event took place. It is formed by using the auxiliary verb "had" in the past perfect tense, followed by "been" and the present participle form of the main verb (-ing form). This tense is used to emphasize the duration or continuity of an action in the past.
