<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">continue to be</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for stay that I've seen before include "Remain; detain" , "Supporting rope or wire" , "Rope or wire used to support a mast" , "Supporter" , "Thin strip used to stiffen a garment" .)
