"He is the best."
Translation:Αυτός είναι κορυφή.
Just FYI: In the English to Greek exercise (Sept 15, 2020), the drop down hints only have καλύτερος (also in fem and pl) and do not have that as an option if you choose multiple choice with multiple words at the bottom. I went with κορυφή and it was marked correct. I guess it's a matter of fixing it so that κορυφή is an option in the drop down hints.
