Terror and fury reflected large risk (7)
I believe the answer is:
imperil
'risk' is the definition.
(I've seen this in another clue)
'terror and fury reflected large' is the wordplay.
'terror' becomes 'imp'.
'and' is a charade indicator (letters next to each other).
'fury' becomes 'ire' (ire is intense rage).
'reflected' says the letters should be written in reverse (letters reflected back).
'large' becomes 'L' (eg in clothes sizes).
'ire' in reverse letter order is 'eri'.
'imp'+'eri'+'l'='IMPERIL'
(Other definitions for imperil that I've seen before include "Place in danger" , "Expose" , "Put in danger" , "Threaten, jeopardise" , "Jeopardize" .)
