The Past Perfect Tense is used to indicate that an action was completed (finished or ""perfected"") at some point in the past before another action happened.

This tense is formed with the past tense form of ""to have"" (Had) plus the past participle of the verb (which can be either regular or irregular in form).

When two actions take place in the past, we use the past perfect tense for the action which took place first and the simple past tense for the action which takes place after.
