"The elephant is an enormous animal."
Translation:Ο ελέφαντας είναι ένα τεράστιο ζώο.
I wrote "Ο ελέφαντας είναι τεράστιο ζώο" and was marked wrong. If the article can be absent in many cases, why is it necessary here?
Yes, agreed, my understanding is that indefinite articles really only need to be used if there could be any confusion over quantity and can be dropped otherwise. Reported!
