Set up or bring about (9)
I believe the answer is:
establish
I believe this is a double definition.
'set up' is the first definition.
(I know that set up can be written as establish)
'bring about' is the second definition.
(thesaurus)
(Other definitions for establish that I've seen before include "Set up on permanent basis, or show to be true" , "Set up or settle firmly in place" , "Create - lodge" , "Institute; set up" , "Found - this sable (anag)" .)
