I believe the answer is:
odium
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">offensiveness</span>' is the definition.<br/ ><span class="explanation-format__explanation">(odium is disgust or offensiveness)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for odium that I've seen before include "reproach" , "Widespread dislike or disgust" , "Offensiveness" , "Antipathy" , "Hatred, repugnance" .)
