"Thank you for your reply."

Translation: Dziękujemy za waszą odpowiedź.

[Glyn617152]

I used 'dziękuję' but the answer was 'dziękujemy'. The english question should read (plural) 'we thank you . . ' otherwise singular would always naturaly be implied here.

Report.

"dziękujemy za waszą odpowiedź" is common in (our company thanks your company) context,

[Xelareip]

Why would "Dziękuję za twoją odpowiedź" not be correct?

[immery]

Report, it is correct.

[immerweiter]

i "Dziękuję za odpowiedź" czy to prawda?

[immery]

in the real world . yes. on duoilingo your is probably missing

[markclark19]

Dziękujemy is we thank you????

[Jellei]

Yes.

[MiriRubin0]

Does za always go with instrumental.

[Jellei]

No, for example here it's Accusative (which looks like Nominative).

When "za" means literally "behind", it takes Instrumental. As for other meanings, the most important are shown here. The problem is of course that different languages use different prepositions in different situations...

[mikegoodwr]

Why should it be "za" instead of dla?

[Jellei]

Well, you never have 1:1 correspondence between prepositions in two languages, and if you thank "for something", that has to be "za coś", with Accusative.

[MaryCarson15]

I thought this verb needed the dative?

[alik1989]

The receiver of the "Thank You" takes dative, but they are not explicitly mentioned in this sentence.

[Jellei]

It could be "Dziękujemy [ci/wam]" and that's Dative. If we thank 'you', then in Polish we usually omit that pronoun, it's just clear from the context. It's not wrong though, I think it sounds formal.
