idle
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">doing nothing</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for idle that I've seen before include "Without work" , "At rest" , "Run out of gear" , "Inert; lazy" , "-- Jack, pantomime character" .)
