I believe the answer is:
mentions
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">refers to briefly</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 mentions that I've seen before include "Makes reference to sonnet I'm changing" , "Touches on" , "Alludes to" , "Speaks or writes about briefly or in passing" , "Refers to briefly" .)
