I believe the answer is:
sylph
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">graceful girl</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for sylph that I've seen before include "Thin, graceful woman" , "Slender and graceful young woman" , "Girl with slender figure" , "Slim person" , "Imaginary (female) being" .)
