Charges a levy for hearing (7)
I believe the answer is:
attacks
'charges' is the definition.
(I know this)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for attacks that I've seen before include "Bouts of illness" , "Fiercely criticises" , "Assaults" , "Assails" , "Charges" .)
