<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">lazing</span>' is the definition.<br/ ><span class="explanation-format__explanation">('idle' can be a synonym of 'laze')</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for idling that I've seen before include "(Engine) ticking over" , "Being indolent" , "'Lazing, loafing (6)'" , "Loafing or just ticking over" , "Not at work" .)
