Accuse (7)
I believe the answer is:
arraign
'accuse' is the definition.
(arraigning is a kind of accusing)
This is all the clue.
(Other definitions for arraign that I've seen before include "Complain about" , "Call before a court to answer an indictment" , "Accuse before tribunal" , "Indict, accuse" , "Accuse of a wrong" .)
