Handsome youth (6)
I believe the answer is:
adonis
'handsome youth' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for adonis that I've seen before include "Handsome Greek loved by Aphrodite" , "Said no to the Greek youth" , "dandy" , "handsome lad" , "male looker" .)
