<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">antithesis</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 opposite that I've seen before include "Totally different; facing" , "Corresponding" , "Facing on the other side" , "Contrary, antipode" , "Directly facing each other" .)
