gone
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">no longer present</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for gone that I've seen before include "Away, departed" , "Departed; used up" , "Absent" , "... saga of 2's civil war" , "Well in the past" .)
