Widespread fire put out (4)
I believe the answer is:
rife
'widespread' is the definition.
(I've seen this in another clue)
'fire put out' is the wordplay.
'put out' indicates an anagram.
'fire' anagrammed gives 'RIFE'.
(Other definitions for rife that I've seen before include "Excessively abundant" , "is everywhere" , "raging" , "Prevalent" , "Widespread like fire" .)
