<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">in danger of falling off</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 loose that I've seen before include "Promiscuous" , "Not bound" , "(Of a garment) a size too big?" , "Lax or at large" , "Hanging" .)
