<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">accuse</span>' is the definition.<br/ ><span class="explanation-format__explanation">(arraigning is a kind of accusing)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(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" .)
