Explications :
Le past perfect exprime un lien entre un moment passé et un autre moment encore plus loin dans le passé. On l'utilise dans un récit au passé, pour parler de quelque chose qui a eu lieu avant celle dont on fait le récit. On peut dire que c'est un passé dans le passé.
Ex : Yesterday my mother cooked dinner, I was disapointed because we had had the same meal the day before.
cooked ==> prétérit ( ça a eu lieu hier )
had had ==> past perfect ( car ça s'est passé le jour d'avant )
( Hier, ma mère a préparé le dîner, j'étais déçu parce que nous avions eu le même repas la veille.)
