disown
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">deny any connection with</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for disown that I've seen before include "Refuse to be connected with" , "Disclaim all connection or relationship with" , "Disinherit or renounce" , "Repudiate, cast off" , "Reject all connection with, refuse to acknowledge" .)
