Beautiful youth (6)
I believe the answer is:
adonis
'beautiful youth' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for adonis that I've seen before include "Aphrodite loved this beautiful youth" , "dandy" , "Most 8 Greek youth" , "Said no to the Greek youth" , "Handsome Gk. youth" .)
