The rush for money (6)
I believe the answer is:
charge
'the rush' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for charge that I've seen before include "Sortie" , "offensive, > explosive > tax" , "Demand in payment" , "Formal accusation" , "Fee; accuse" .)
