"Why are you in a hurry?"

Translation: Dlaczego się śpieszysz?

[YassineAl]

Can't it be 'dlaczego śpieszysz się' ?

[YarkoRab]

It's perfectly correct, believe me. I reported it ...

[alik1989]

We consider it a stylistic mistake to end a sentence with an unaccented pronoun if there are other word order options available.

[YarkoRab]

Whatever, it is correct in everyday use, however, it's probably less frequent.

[alik1989]

Well, I did a corpus search, and it turns out that in such short sentences like this one, it's about 50 times less common. So "probably less frequent" is definitely a massive understatement.
It's a beginner course's prerogative to reject unusual and rare word orders.

[mihxal]

"się" is usually not used at the end of the sentence. Such word order is not natural.

[KornDog513]

Pani is the subject here, right? It is necessary?

[Jellei]

If you use Formal You, you cannot omit the subject. "Dlaczego się śpieszy" without "pani" is just "Why is he/she/it in a hurry?", and the subject would need to be known from the context.

[Ali759455]

Spieszyć i śpieszyć są poprawne.

[Jellei]

I obie formy są akceptowane.

[PetrDiblik]

Does "czemu" really mean "why"? :-O

[Jellei]

Yes it does.

Also it's Dative of 'co', which you may have suspected.

[Dominianio]

I chose the right option, but if asked to translate the sentence, I normally would say, "Czemu pani się spieszy?". Is this also correct? If so, is one word order better than the other one and if so, why?
