I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">to skin</span>' is the definition.<br/ ><span class="explanation-format__explanation">(flay can mean to take something's skin off)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for flay that I've seen before include "fleece" , "Skin alive" , "Strip skin from (a body)" , "Strip skin off by whipping" , "thrash" .)
