The past perfect and continuous tense follows the format: subject + had + been + -ing form of the verb, such as: I/We/You/He/She/It/They + had + been + -ing form of the verb.
It is used for action or states of being had been happening in the past before something else, for example: I had been studying in my room when my little sister barged in.
