"To je dobrá káva."

Translation: This is good coffee.

[AJK5599]

"This coffee is good" was not accepted. Anyone?

[VladaFu]

This is a different sentence. "Ta káva je dobrá."

[ClarkBHM]

Maybe so, but in English this is interchangeable. Both should be accepted.

[VladaFu]

It won't be. Be prepared that this distinction will be observed in many other sentences in this course.

[Alex.Eisner]

Is it "dobrá káva" and not "dobrou kávu" becausenin this lesson coffee comes in as a nomitive and not an accusative? Like voda/vodu?

I learn on my phone so the tips don't show up.

[BoneheadBass]

Yes, they are nominative forms,. You can access the Tips and Notes on a mobile device by getting to Duolingo through a mobile browser. They are not currently available in the apps.
