<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">legal wrongdoing</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for tort that I've seen before include "Private wrong for which damages may be claimed" , "Wrongful act (in law)" , "Trot after legal wrong liable to damages" , "Private or civil wrong - trot after it" , "Trot to get legal wrong" .)
