Learn Swedish: Tack vare spionen fick vi höra vem som avlyssnade agenten. - Thanks to the spy, we got to hear who eavesdropped on the agent.

Using få + a verb of perception (like höra, se, or veta) focuses on acquiring new information. While vi hörde simply means 'we heard', vi fick höra emphasizes the moment of finding out, often translating best to 'we found out', 'we were told', or 'we got to hear'.

Why is the verb fick placed before the subject vi?

This is the V2 (verb-second) rule in action. The sentence starts with the adverbial phrase Tack vare spionen (Thanks to the spy). Because this phrase takes up the first position, the verb fick must immediately follow in the second position, pushing the subject vi to the third position.

Why is there a som after vem in this sentence?

This is an indirect question acting as a subordinate clause. In Swedish, when a question word like vem (who) or vad (what) is the subject of its clause, you must add som. If the sentence were about whom the agent eavesdropped on (making the agent the subject), it would just be vem agenten avlyssnade without som.

Could I say på grund av spionen instead of tack vare spionen?
