Terribly resent, though accepting, the small bribe (9)
I believe the answer is:
sweetener
'small bribe' is the definition.
'sweetener' can be an answer for 'bribe' (I've seen this before). I am unsure of the 'small' bit.
'terribly resent though accepting' is the wordplay.
'terribly' indicates anagramming the letters.
'though' becomes 'wee' (I can't justify this - if you can you should give a lot more credence to this answer).
'accepting' indicates putting letters inside.
'resent' is an anagram of 'stener'.
'stener' enclosing 'wee' is 'SWEETENER'.
'the' is the link.
Can you help me to learn more?
(Other definitions for sweetener that I've seen before include "Bribe (informal)" , "carrot" , "Saccharin, for example" , "backhander" , "substitute going in at teatime?" .)
