I believe the answer is:
visit
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">drop by</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for visit that I've seen before include "See; temporary stay" , "Drop in; frequent" , "Call on - stay" , "pop by" , "Come to see" .)
