Bribe with sugar (9)
I believe the answer is:
sweetener
This clue is a double definition.
'bribe' is the first definition.
(thesaurus)
'sugar' is the second definition.
(thesaurus)
'with' acts as a link.
(Other definitions for sweetener that I've seen before include "Bribe (informal)" , "Extra inducement" , "backhander" , "Eg, sugar" , "Eg, saccharin" .)
