Violate the sacred (9)
I believe the answer is:
desecrate
'violate the sacred' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for desecrate that I've seen before include "Spoil" , "Secreted a means to treat something sacred with disrespect" , "Violate the sacred" , "Profane" , "Treat (something sacred) with great disrespect" .)
