Are "niks" and "niets" completely interchangeable?
Same question here. Any help?
Yes, they are. With the exception that you should avoid "niks" in formal writing. But otherwise they mean exactly the same thing.
Why is it not "Zij wilt...?"
Because willen is somewhat irregular, see here
It's easy to remember when the equivalent English verb is also not conjugated in the 3rd person singular (She will, not She wills).
should it be zil wil niks te zeggen
"willen" is not followed by "te" + infinitive. If you want to use such a construction here, you can use the verb "wensen".
Zij wil niks zeggen.
No matter how much I listen and see the solution, I just can't hear the word "anything" in there.
Any alternative choices?
'she wants to say nothing' but im assuming they went for the more natural english translation rather than the literal
Why was niets wrong ?
How does one know when to say "Zij" or "Ze" ?
