I believe the answer is:
topic
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">something to talk about</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for topic that I've seen before include "Question" , "Matter for an argument" , "Subject (eg, of text)" , "Subject (of a talk, etc)" , "Subject (of, eg, speech)" .)
