In shock, return edition full of nasty sex (10)
I believe the answer is:
gobsmacked
'in' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives sometimes define each other.
'shock return edition full of nasty sex' is the wordplay.
I cannot quite understand how this works, but
'edition' could be 'ed' (abbreviation) and 'ed' is found in the answer.
'of' could be 'o' and 'o' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gobsmacked that I've seen before include "Stunned" , "utterly astonished" , "Dumbfounded" , "bowled over" , "Amazed" .)
