Past Perfect Tense

Introduction

Past perfect verbs are used to talk about actions that happened before a point of time or an action in the past.

The reference to the past should show the order of the two actions. The action that happened first is in the past perfect, while the action that happened later (closer to the present) is in the past simple.

Examples:

  • She had written two books before she signed up for the competition.
(1st: She wrote …; 2nd: She signed up …)
  • They had visited several places by the time we spoke to them.
(1st: They visited …; 2nd: We spoke …)
  • He had cleaned up the area when the police arrived.
(1st: He cleaned up …; 2nd: The police arrived.)

Forms

In the past perfect tense, the auxiliary had and the past participle of the verb are used in all forms and with all subjects (I, we, you, they, he, she, it).

Affirmative Sentences:

Subject + had + past participle 

  • She couldn’t sleep because she had eaten a heavy meal.
