Incitement to action after the end of the crime is arousing feeling (7)
I believe the answer is:
emotive
'arousing feeling' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for emotive that I've seen before include "Affecting, moving" , "able to get going" , "Arousing strong feeling" , "Tending to arouse feelings" , "Highly-charged" .)
