Bribe, inducement (9)
I believe the answer is:
sweetener
I believe this clue is a double definition.
'bribe' is the first definition.
(I've seen this before)
'inducement' is the second definition.
(I've seen this before)
(Other definitions for sweetener that I've seen before include "pill to replace sugar" , "Substance like sugar" , "Eg, sugar" , "Bribe (informal)" , "backhander" .)
