<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">curvy</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 sinuous that I've seen before include "Full of curves, bends" , "Having many curves and turns" , "Snakelike" , "Having many curves, undulating" , "Lithe, supple; curvy" .)
