Amazing chapter removed and editor's panic-stricken (9)
I believe the answer is:
terrified
'panic-stricken' is the definition.
(I know that panic-stricken can be written as terrified)
'amazing chapter removed and editor's' is the wordplay.
I cannot really understand how this works, but
'editor' could be 'ed' (abbreviation) and 'ed' is present in 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 terrified that I've seen before include "Extremely frightened" , "Greatly frightened" , "Panic-stricken - dire refit (anag)" , "Scared stiff" .)
