I believe the answer is:
topic
<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">theme</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >'<span class="explanation-format__original">issue</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ ></span>
(Other definitions for topic that I've seen before include "might this be hot?" , "Subject (for conversation, etc)" , "Subject (eg, of text)" , "'Theme, subject (5)'" , "Talking point" .)
