<span class="explanation-format__ClueExplanation">I believe this clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">vulnerable</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >'<span class="explanation-format__original">sensitive</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that sensitive can be written as tender)</span><br/ ><br/ ></span>
