Blissful soldier with youngster returning is embraced (9)
I believe the answer is:
paradisal
'blissful' is the definition.
(like paradise)
'soldier with youngster returning is embraced' is the wordplay.
I cannot quite understand how this works, but
'soldier' could be 'para' (short for paratrouper) and 'para' is found in the answer.
'is' is present in the answer.
The remaining letters 'dal' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for paradisal that I've seen before include "Like heaven or Eden" , "Perfect" .)
