I believe the answer is:
evacuate
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">make empty</span>' is the definition.<br/ ><span class="explanation-format__explanation">(evacuating is a kind of making empty)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for evacuate that I've seen before include "Completely empty" , "In wartime, remove civilians from cities to safety of countryside" , "Move people from their homes" , "rescue from bad situation" , "Get out of" .)
