<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">symbol</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >'<span class="explanation-format__original">indication</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that sign is a type of indication)</span><br/ ><br/ ></span>
