Bond heard hint about Republican self-flagellation (5,4)
I believe the answer is:
guilt trip
'republican self-flagellation' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'bond heard hint' is the wordplay.
'bond' becomes 'gilt' (I've seen this before).
'heard' indicates a 'sounds like' (homophone) clue.
'hint' becomes 'trip' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'gilt' sounds like 'guilt'.
'guilt'+'trip'='GUILT TRIP'
'about' is the link.
Can you help me to learn more?
(Other definitions for guilt trip that I've seen before include "Prolonged feeling of shame" , "Evidence of stricken conscience" .)
