<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">winner</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that winner can be written as victor)</span><br/ ><br/ >'<span class="explanation-format__original">champion</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ ></span>
