I believe the answer is:
innocent
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not guilty</span>' is the definition.<br/ ><span class="explanation-format__explanation">('innocent' is the opposite to 'guilty')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for innocent that I've seen before include "Guiltless or guileless" , "Without blame or without guile" , "white" , "Virgin" , "Pope" .)
