"Do you know Geography?"

Translation: Ξέρεις Γεωγραφία;

[spdl79]

Is "ξέρεις τη γεωγραφία;" actually incorrect?

[troll1995]

Yes, because using the definite article when you talk about something non-specific is wrong (the question above talks about geography in general, without any other context). If the question was "Do you know Greece's geography?" then an article would be needed, because you are talking about a particular geography. Ξέρεις την γεωγραφία της Ελλάδας;

[spdl79]

Ah, yes, of course. That makes sense, thanks so much Troll!

[Phil682961]

Would you still need the definite article in the nominative? For example "μου αρέσει η Γεωγραφία" ?

[D_..]

Yes!

[J.N7MH]

Please accept Ξέρετε Γεωγραφίας

[Marva441926]

I think that the answer must be Ξέρετε Γεωγραφία with Γεωγραφία in the accusative, not the genitive.

[Norman921621]

Why is " Ξέρετε γεωγραφία; " wrong ?

[jurgen_maes]

Ξέρεις η Γεωγραφία;

[Marva441926]

See Troll's answer to spdl79 above. It is not correct to use the definite article here because the question is about geography in general.
