Put at risk, stop rage (8)
I believe the answer is:
endanger
'put at risk' is the definition.
(I've seen this in another clue)
'stop rage' is the wordplay.
'stop' becomes 'end' (synonyms).
'rage' becomes 'anger' (I've seen this before).
'end'+'anger'='ENDANGER'
(Other definitions for endanger that I've seen before include "Put in jeopardy" , "Jeopardize" , "Put in harm's way" , "Hazard" , "Threaten" .)
