<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">tire</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 flag that I've seen before include "Emblematic rectangular piece of fabric" , "what Amundsen planted" , "Droop with tiredness" , "part of pavement" , "Rectangular piece of fabric used as a signalling device" .)
