This has to be the most confusing first read I've ever done XD
I am glad I am not the only on confused by this sentence.
Good thing I can't imagine any time I would ever use or hear it.
I was reading "...för att..." to mean because and getting very confused :-/
bestämma sig för att = decide to.
Is that so?
Just feel weird to see putting "för" and "att" together.
They're not really together - bestämma sig för is one unit, and the att just serves to introduce the verb, like the "to" in English.
Does this mean that she will have decided to go (away, to the store, home, etc.), or that she will have decided, specifically, to walk somewhere?
Either is a perfectly reasonable interpretation.
How can we write this sentence with....GOING TO....
"She is going to have decided to leave/go/walk."
Why is chosen not accepted as a synonym for decided?
That would be valt rather than bestämt.
