Show contempt for (5)
I believe the answer is:
flout
'show contempt for' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for flout that I've seen before include "Mock" , "Show contempt for, defy" , "Ignore (rule)" , "Defy (orders etc)" , "Treat with contempt" .)
