I believe the answer is:
drifts
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">moves aimlessly</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 drifts that I've seen before include "problems with snow" , "Wanders around" , "proceeds without purpose" , "piles!" , "Moves slowly, carried by a current of air or water" .)
