<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">hate</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that despise is a more specific form of the action hate)</span><br/ ><br/ >'<span class="explanation-format__original">abhor</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ ></span>
