<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">juryman</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for juror that I've seen before include "person to deliver verdict" , "One of twelve in a box?" , "One of twelve in court?" , "Trial panellist" , "One of those responsible for verdict" .)
