<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">wound reminder</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 scar that I've seen before include "Limestone cliff or outcrop" , "Mark of former injury" , "Effect of unpleasant experience" , "Mark of a wound remaining on the skin" , "Old-wound mark" .)
