Colloquially, to create a commotion (5,4)
I believe the answer is:
raise cain
'create a commotion' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for raise cain that I've seen before include "Make an uproar - lift Abel's brother" , "Make a lot of trouble" , "Make a big commotion (5.4)" , "Create an uproar - elevate murderer" , "Create an unholy row - elevate murderer" .)
