Question

past perfact continuous tenses​

Answer 1

The past perfect continuous tense (also known as the past perfect progressive tense) shows that an action that started in the past continued up until another time in the past. The past perfect continuous tense is constructed using had been + the verb's present participle (root + -ing).

The Past Perfect Continuous tense is like the Past Perfect tense, but it expresses longer actions in the past before another action in the past. For example: Ram started waiting at 9am. I arrived at 11am.
