Uproar about editor making cut (9)
I believe the answer is:
reduction
'cut' is the definition.
(thesaurus)
'uproar about editor' is the wordplay.
'uproar' becomes 'ruction' (I've seen this before**).
'about' means one lot of letters goes inside another.
'editor' becomes 'ed'.
'ruction' placed around 'ed' is 'REDUCTION'.
'making' acts as a link.
(Other definitions for reduction that I've seen before include "Introduce (anag) - decrease" , "Lessening" , "from nine to five, for example" , "Drop in price" , "cutback!" .)
