<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">horn</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that horn can be written as hooter)</span><br/ ><br/ >'<span class="explanation-format__original">nose</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(hooter can informally mean someone's nose)</span><br/ ><br/ ></span>
