"Why is it dark in here?"

Translation: Dlaczego jest tu ciemno?

What's wrong with "dlaczego jest ciemno tu"?

[immery]

I have no idea why, but it is definitely wrong. Like really weird. I think we do not like "Tu" at the end. "tutaj" would be less weird but still not ok.

[Galois33]

Could you also have "Dlaczego tu jest ciemno"?

[marbleox]

That is what I wrote and it was accepted.

Why did it mark wrong, "Czemu jest ciemno tutaj?"

[va-diim]

It also marked as incorrect, "Dlaczego jest ciemno tutaj?".

[Jellei]

I don't know. It's maybe not wrong, but sounds too strange to me. If you ask a question like that, logically the part about being 'dark' is important, and not 'here', so this is rather a surprising word order to me...

[va-diim]

OK, thank you

Czy mogę teoretyczne też "czemu" zamiast "dlaczego" użyć?https://sjp.pwn.pl/poradnia/haslo/czemu-czy-dlaczego;9199.html

[Jellei]

Tak, zawsze.

What is the difference between tutaj and tu?

[Jellei]

Rather only a stylistic one, they mean exactly the same.

One thing: if you really want to use it at the end of the sentence (which I would generally advise against, it puts a strong emphasis on "here"), at least use "tutaj".

In Russian, Dlia ciego tut tiemno? "For what [reason] is it dark here?"
