Delightful prince? (8)
I believe the answer is:
charming
I believe this is a double definition.
'delightful' is the first definition.
(I've seen this before)
'prince' is the second definition.
(Prince Charming)
(Other definitions for charming that I've seen before include "Delightful, attractive" , "Lovely! - with 15a" , "Beguiling, enchanting" .)
