Handsome Greek youth (6)
I believe the answer is:
adonis
'handsome greek youth' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for adonis that I've seen before include "Handsome youth - said no (anag)" , "Handsome youth - boy from Greek mythology" , "Beautiful young man" , "male looker" , "lovely man" .)
