Arouse, provoke (9)
I believe the answer is:
stimulate
I believe this is a double definition.
'arouse' is the first definition.
(I know that arouse can be written as stimulate)
'provoke' is the second definition.
(I know that provoke can be written as stimulate)
(Other definitions for stimulate that I've seen before include "Rouse" , "Kindle?" , "Mutilates so as to make more active" , "Excite the feelings of" , "fire" .)
