What does fällen do for this sentence? i.e., if removed, how would the sentence change?
“Entscheidung” and “fällen” go together, i.e. “fällen” is the verb that is normally used for “Entscheidungen”.
It’s like in english: you “pay your respects” instead of “give respects” or something.
I think it’s called a collocation, when a verb and a noun belong together.
if removed, how would the sentence change?
There would be a verb missing.
