I assume you are asking about Ancient Greek. IGNORE all the Greeks that are about to say ἄρωμα arōma. The ancient meaning of that word, per the Liddell–Scott dictionary, is aromatic herb or spice; not fragrance.

On the other hand, a young, vibrant, overgrown student politician, who disputes the status quo, who resents the enmeshment of Church and State, who never wears a tie, who got a whole nation’s hopes up (in a not very hopeful-looking way, granted), and who can mug for the camera:
Oh, Alexis is cooler alright.
Whether “cool” is what Greece actually needs out of its leadership is a quite different question.
