Retaliate to get campaign returned (5,4)
I believe the answer is:
fight back
'retaliate' is the definition.
The answer and definition can be both related to competing as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'get campaign returned' is the wordplay.
'get' is a charade indicator (letters next to each other).
'campaign' becomes 'fight' (I've seen this before).
'returned' becomes 'back' (I've seen this before).
'fight'+'back' is 'FIGHT BACK'.
'to' is the link.
Can you help me to learn more?
(Another definition for fight back that I've seen is " Resist".)
