I believe the answer is:
recline
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">lie back</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 recline that I've seen before include "Lie on the back or side" , "Lie back and take it easy" , "Adopt horizontal or leaning position" , "Lie in a comfortable position" , "Lounge" .)
