"Ten projekt to dla niej duży stres."

Translation: This project is very stressful for her.

[Jack.Elliot]

the same sentence but with" to" instead of "for"

[Jellei]

OK, added.

[Jack.Elliot]

you are welcome

How about "This project is a great source of stress for her", translating "stres" as "source of stress" (and "duży" as "great")?

[Jellei]

Well... but we can easily translate your English sentence literally, so it's "Ten projekt jest dla niej źródłem wielkiego stresu".

[DariuszCzu1]

Ten projekt jest dla niej bardzo stresujący

[Jellei]

I see that this sentence has the EN -> PL translations blocked, probably because it translates a Polish noun into an English adjective and we don't teach "stresujący". But sure, your answer would be perfectly correct, if there was anywhere to put it ;)

This is one of those strange differences in English and Polish sentence contruction...

The literal translation seems to be "This project is a big stress for her" which actually works perfectly fine in English, and retains stress as a noun instead of translating it into an adjective

Could you also translate "This project is very stressful [for/to] her" as either Ten projekt jest dla niej bardzo stresowy" or even use dative case and say "Ten projekt jest jej bardzo stresowy"

[Jellei]

No, I don't think this adjective works in the Polish sentence, and the Dative construction is a rather unusual one, it may work sometimes, but that probably will sound dated (see? Dative, dated, hehe).

Perhaps "stresogenny" could work, I can see that English has a similar word: "stressogenic". And "stresujący" for sure.
