Past Perfect




FORM

[had + past participle]
Examples:
  • You had studied English before you moved to New York.
  • Had you studied English before you moved to New York?
  • You had not studied English before you moved to New York.

Completed Action Before Something in the Past

The Past Perfect expresses the idea that something occurred before another action in the past. It can also show that something happened before a specific time in the past.
Examples:
  • had never seen such a beautiful beach before I went to Kauai.
  • I did not have any money because I had lost my wallet.
  • Tony knew Istanbul so well because he had visited the city several times.
  • Had Susan ever studied Thai before she moved to Thailand?
  • She only understood the movie because she had read the book.


IMPORTANT Specific Times with the Past Perfect

Unlike with the Present Perfect, it is possible to use specific time words or phrases with the Past Perfect. Although this is possible, it is usually not necessary.
Example:
  • She had visited her Japanese relatives once in 1993 before she moved in with them in 1996.
