Questions & Answers about Ljudboken lyssnade jag på igår.
Why is the object Ljudboken at the beginning of the sentence instead of the subject jag?
In Swedish, you can move the object to the front of the sentence to emphasize it. This is common when you want to make that object the main topic. Because of the V2 rule (the verb must be the second idea in the main clause), the verb lyssnade must come right after Ljudboken, which forces the subject jag to swap places and come after the verb.
Why is the preposition på hanging out by itself after jag?
The full verb phrase is lyssna på (to listen to). Normally, you would say Jag lyssnade på ljudboken igår. Because Ljudboken was moved to the front of the sentence for emphasis, på gets left behind (or stranded). This happens in English too, like when we say 'The audiobook I listened to'.
Could I just say 'Ljudboken lyssnade jag igår' without på?
No, the preposition på is absolutely required here. In Swedish, the verb lyssna needs på whenever you specify what you are listening to. If you drop it, the sentence sounds incomplete, just like saying 'The audiobook I listened yesterday' in English.
Since the current lesson is about the instrumental 'med', how would I add that I listened 'with headphones'?
