The Past Perfect Continuous Tense
The Past Perfect Continuous (also called Past Perfect Progressive) describes an action that was in progress before another action in the past. It emphasizes the duration of the earlier action.

Examples: “I had been studying for two hours when she arrived.” “They had been waiting for 30 minutes before the bus came.”
Uses
