The Persian past perfect is made up of two parts:
1. past participle of the verb
2. corresponding past simple tense form of the verb “to be”
Here is an example for the verb “to read”:
[I] had read
[you] had read
[he/she/it] had read
[we] had read
[you (pl.)] had read
[they] had read
Persian past perfect is almost exactly like English past perfect.
