I believe the answer is:
debunked
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">exposed as false</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 debunked that I've seen before include "ruined reputation?" , "Showed to be false or incorrect" , "Showed up as false or exaggerated" , "Uncovered pretentious or false claims and ideas" , "Cut down to size!" .)
