I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">does penance</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 atones that I've seen before include "Makes up for wrong done with a stone" , "Makes up for injury inflicted" , "Makes redress" , "Makes up for injury or offence" , "Makes reparation" .)
