Bribe sometimes taken with coffee? (9)
I believe the answer is:
sweetener
I believe this is a double definition.
'bribe' is the first definition.
(I've seen this before)
'sometimes taken with coffee?' is the second definition.
(sweetener might be added to coffee)
(Other definitions for sweetener that I've seen before include "Eg, saccharin" , "Saccharin, for example" , "Extra inducement" , "Something tart could do with this" , "pill to replace sugar" .)
