Bring charges as copper's caught by super (6)
I believe the answer is:
accuse
'bring charges' is the definition.
(thesaurus)
'copper's caught by super' is the wordplay.
'copper's' becomes 'cus' (chemical symbol).
'caught by' indicates putting letters inside.
'super' becomes 'ace' ('ace' can be a synonym of 'super').
'cus' put within 'ace' is 'ACCUSE'.
'as' acts as a link.
(Other definitions for accuse that I've seen before include "Charge (someone) with an offence" , "Make charge against" , "Impeach" , "Indict, blame wrongdoing on" , "Impute fault to, indict" .)
