Criticise mean bribe (3,2)
I believe the answer is:
get at
I believe this clue is a triple definition!
'criticise' is the first definition.
(I've seen this before)
'mean' is the second definition.
(as in what a speaker means or is 'getting at')
'bribe' is the third definition.
(I've seen this in another clue)
(Other definitions for get at that I've seen before include "Reach - mean - attack verbally" , "Nobble; gain access to" , "Unfairly influence" , "Intend" , "Criticise (someone)" .)
