I believe the answer is:
dangle
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">hang freely</span>' is the definition.<br/ ><span class="explanation-format__explanation">(dangling is a kind of hanging freely)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for dangle that I've seen before include "wave" , "Hang so as to swing freely" , "Temptingly offer" , "Hang provocatively" , "Hang loosely or swing" .)
