I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">constable</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that constable can be written as policeman)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for policeman that I've seen before include "Rozzer" , "Bobby" , "Member of the force" , "Member of the Garda, say" , "He's responsible for the maintenance of public order" .)
