hangman
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">official executioner</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for hangman that I've seen before include "wordgame?" , "Word game - executioner" , "He suspends" , "Pencil-and-paper game for two" , "official suspending offenders" .)
