Journalist entering fray, cut (9)
I believe the answer is:
reduction
'cut' is the definition.
(I've seen this before)
'journalist entering fray' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'entering' is an insertion indicator.
'fray' becomes 'ruction' (I can't explain this - if you can you should give a lot more credence to this answer).
'ed' inserted into 'ruction' is 'REDUCTION'.
Can you help me to learn more?
(Other definitions for reduction that I've seen before include "cutback!" , "Lessening" , "Drop in price" , "from nine to five, for example" , "Introduce (anag) - decrease" .)
