Brought about and violently driven to top of cliff (9)
I believe the answer is:
contrived
'brought about' is the definition.
(contrive can mean to bring about or engineer)
'violently driven to top of cliff' is the wordplay.
'violently' indicates anagramming the letters.
'top of' indicates taking the first letters.
The initial letter of 'cliff' is 'c'.
'driven'+'to'+'c'='driventoc'
'driventoc' with letters rearranged gives 'CONTRIVED'.
'and' acts as a link.
(Other definitions for contrived that I've seen before include "Artificial" , "orchestrated" .)
