Will be apoplectic if edited review reveals shortfall (7)
I believe the answer is:
deficit
'shortfall' is the definition.
(I know that shortfall can be written as deficit)
'will be apoplectic if edited review' is the wordplay.
'will' says to put letters next to each other (I've seen this in other clues).
'be apoplectic' becomes 'tic' (I can't explain this - if you can you should believe this answer much more).
'edited' becomes 'ed' (publishing abbreviation).
'review' says the letters should be written backwards.
'tic'+'if'='ticif'
'ticif' next to 'ed' is 'ticifed'.
'ticifed' reversed gives 'DEFICIT'.
'reveals' acts as a link.
Can you help me to learn more?
(Other definitions for deficit that I've seen before include "Shortage" , "Arrears" , "Shortfall in revenue" , "Want" , "There's something lacking" .)
