"Dlaczego ta rzecz jest droga?"

Translation: Why is this thing expensive?

[MichThatsMe]

Perhaps "item" should be accepted as rzecz?

[Jellei]

I'd probably translate "item" to "przedmiot", but okay, added.

Ok, as an experiment I tried "Why is this expensive" and it was rejected. In English, in a sentence like this, thing is implied and is very rarely explicitly stated.
Hmm. Come to think of it it might be a step too far. I suspect "Dlaczego to jest drogie" would be the equivalent, but I'll leave this here anyway.

[Jellei]

"Dlaczego to jest drogie?" (or even more probably, "takie drogie" = "so expensive") seems to be a more probable question in Polish as well. But well, it's not what was written here ;)

"Why is this thing so expensive?" was rejected. I see a comment suggesting "takie drogie" would be "so expensive". Can you elaborate?

[Jellei]

In this particular sentence, the grammatically right form would be "taka droga".

I don't know what to say more, "so" is an intensifier, and so is "taka".

"Why this thing is expensive" has been rejected

[Jellei]

Yes, "Why this thing is expensive" is not a correct question in English.
