Mean to cheat over money (7)
I believe the answer is:
connote
'mean' is the definition.
(to connote something is to mean or suggest it)
'cheat over money' is the wordplay.
'cheat' becomes 'con' (conning is a kind of cheating).
'over' means one lot of letters go next to another (in a down clue, some letters go over others).
'money' becomes 'note' (I can't explain this - if you can you should believe this answer much more).
'con'+'note'='CONNOTE'
'to' is the link.
Can you help me to learn more?
(Other definitions for connote that I've seen before include "Imply, state indirectly" , "Imply, suggest" , "Imply as a consequence" , "Imply in addition to the literal meaning" .)
