<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">dead skin</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for cuticle that I've seen before include "Dead skin at nail's base" , "Dead skin on hand" , "finger has one" , "layer of protection" , "Skin at foot of nail" .)
