Word order and the little words - those we used to call ‘joining words’ - get me almost every time. I’ve begun to include them if the word bank offers them, whether I understand their usage or not. Seems like cheating to me.
Agree, they are little devils! But have found they are getting a bit easier the longer I practise. Don't agree it's cheating, rather a way of getting them correct which hopefully will sink in eventually.
"At være bange/At være bange for" One describes the state that you are in, the other what you are scared of, so the "for" is used to connect the state of being with the reason. Without "for" the sentence doesn't work as intended, it would be two unconnected sentences stringed together.
