What about: "It's all I know about Kyiv."?
It was a missing alternative.
2 years is gone. and it still remains "a missing alternative."
Why isn't it "its everything I know about Kyiv"
I wrote: This is everything what I know about Kyiv.
But it is incorrect, word 'what' is problem.
I see word що (what) in Ukrainian example.
Why is the word 'що' necessary to the sentence. Surely it means exactly the same without this word?
"It is all i know" sounds more correct
