The past perfect continuous tense is used to describe an ongoing action that started in the past and continued up until another point in the past. 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).

The past perfect continuous tense is often used to emphasize the duration of an action or to show the cause and effect relationship between two past actions. It is commonly used in storytelling, when describing events that occurred before another event in the past.
It is important to note that the past perfect continuous tense is not commonly used in everyday conversation, but it is useful in writing and formal contexts to provide a clear timeline of past events.
