Cheat put on record over hack (7)
I believe the answer is:
finagle
'cheat' is the definition.
(I've seen this before)
'put on record over hack' is the wordplay.
'put on record' becomes 'file' (synonyms).
'over' indicates putting letters inside.
'hack' becomes 'nag' (synonyms).
'file' placed around 'nag' is 'FINAGLE'.
(Other definitions for finagle that I've seen before include "Dishonestly obtain" , "Swindle" , "cheat" .)
