Questions & Answers about Vi hade köpt biljetter innan filmen började.
What tense is hade köpt, and what does it express?
It’s the pluperfect (Swedish: pluskvamperfekt). You form it with hade + the verb’s supine (here: köpt). It places one past event as completed before another past reference point (here, before the time when the movie started).
Why is it köpt and not köpte?
Because hade must be followed by the supine form, köpt. The simple past (preterite) of the verb is köpte. Paradigm: köpa – köper – köpte – köpt.
Can I just say Vi köpte biljetter innan filmen började? Does it change the meaning?
Yes, that sentence is also correct and very natural. Innan already establishes the time order. Using the pluperfect (hade köpt) adds extra clarity or emphasis that the buying was completed before the reference past event, but the basic meaning is the same.
Why use innan instead of före here?
Use innan before a clause (something with a verb), like innan filmen började. Före is a preposition and goes before a noun/pronoun: före filmen, före mig. You can say före det att filmen började, but it’s bulky; standard Swedish prefers innan with clauses.
