Prophet and diminutive journalist grow furious (3,3)
I believe the answer is:
see red
'grow furious' is the definition.
(I've seen this before)
'prophet and diminutive journalist' is the wordplay.
'prophet' becomes 'seer' (both can mean someone who tells the future).
'and' is a charade indicator (letters next to each other).
'diminutive journalist' becomes 'ed' (short for editor. I am not sure about the 'diminutive' bit.).
'seer'+'ed'='SEE RED'
Can you help me to learn more?
(Other definitions for see red that I've seen before include "Lose temper as bull might" , "get angry" , "Lose temper like raging bull" , "lose control" , "Become suddenly angry" .)
