Zur Wiederholung des past perfect sei das Kapitel 8.5 empfohlen. Die Verlaufsform des past perfect unterliegt wiederum derselben Logik. Das Verb to be wird ins past perfect versetzt und das Partizip I wird angehängt. Der Unterschied zur Verlaufsform im present perfect ist nur die Form des Hilfsverbs to have.

Beispiel
to have (past) = past perfect + Partizip II + Vollverb + Endung -ing = Verlaufsform
