Rage after final part is put at risk (8)
I believe the answer is:
endanger
'is put at risk' is the definition.
(I've seen this before)
'rage after final part' is the wordplay.
'rage' becomes 'anger' (I've seen this in another clue).
'after' says to put letters next to each other.
'final part' becomes 'end' (I've seen this before).
'anger' put after 'end' is 'ENDANGER'.
(Other definitions for endanger that I've seen before include "Dan Green (anag.)" , "Put in peril" , "Pose a threat to" , "Put in trouble" , "Put in harm's way" .)
