Pluperfect

English Grammar | Pluperfect |  The plu−perfect is formed with the auxiliary HAD, followed by the past participle of the
main verb:

• He had always wanted to travel in Africa.
• She had already left when Philippe arrived.
• I bought the book that Corinne had recommended to me.

The plu−perfect shows that the action has been done before another action (in the past).
Adverbs such as "already" reinforce this impression.

• She learned to love the dog that had bitten her the week before.
• When I got home, I had already heard the bad news.
• The children ate all the cookies that their father had bought.

The plu−perfect is often used in hypothetical expressions with "if", in conjunction with the
past conditional:

• I would not have come if I had known he was ill.
• With the adverb "just", the plu−perfect indicates the immediate past in a past context:
• He had just eaten lunch when I arrived.
