"bad night"

Translation: špatná noc

[ettoreg60]

Then I guess 'noc' is feminine, right?
So why is 'good night' translated as 'dobrou noc' instead of 'dobrá noc'?

[endless_sleeper]

Yes, noc is feminine.

I usually explain it like this: dobrou noc uses accusative dobrou because it's a shortening of Přeji ti/vám dobrou noc. 'I wish you (sg/sg formal+plural) a good night.' You use accusative for the object of a verb.

What does accusative mean? And what is object of an accusative?

[VladaFu]

The grammatical case used for direct objects. I suggest waiting for a few lessons, it will come soon. Or you can look into https://en.wikipedia.org/wiki/Grammatical_case

Why if i just accidentally placed a emoji is this incorrect?

If you used the Report button to send your rejected answer directly into the system, someone should be able to tell you why it was rejected. Could be something as simple as a Duo rule that "emojis don't belong in translations."
