"She is professional."
Translation:Αυτή είναι επαγγελματίας.
Is επαγγελματική the adjective and επαγγελματίας the noun? So "She is professional" versus "She is a professional"?
Ι was wondering this same thing...based on Theo's answer, it seems the English translation is wrong (unless the Greek words are the same other than being different lexical categories).
