Past perfect (hade)

The Past Perfect (hade + supinum)

The past perfect describes an action that was completed before another event in the past. It is formed just like its English equivalent: use hade (had) followed by the supinum form of the verb.

I had forgotten the wallet at home.
Jag hade glömt plånboken hemma.

As with the present perfect, sentence adverbs like inte (not) or redan (already) come directly after hade in a main clause.

We had not locked the door yesterday.
Vi hade inte låst dörren igår.
The boss had already changed the plan.
Chefen hade redan ändrat planen.

Connecting Past Events

The past perfect is often combined with the simple past to clarify the sequence of events. This is especially useful when describing unexpected changes or realizing a mistake. Use conjunctions like att (that), därför att (because), or innan (before) to link these events.

I realized that I had made a mistake.
Jag insåg att jag hade gjort ett misstag.
He missed the train because he had overslept.
Han missade tåget därför att han hade försovit sig.
We had cancelled the booking before we realized the mistake.
Vi hade ställt in bokningen innan vi insåg misstaget.

The action with hade always happens first chronologically, even if it appears later in the sentence.

I changed the plan because he had missed the meeting.
Jag ändrade planen därför att han hade missat mötet.
