I believe the answer is:
item
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">individual article</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for item that I've seen before include "Part of a list" , "couple making out {TIME}..." , "Individual article or unit" , "Feature" , "Detail - entry" .)
