<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not quite closed</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 ajar that I've seen before include "Mourn" , "Partly open" , "(Of door) slightly open" , "not slammed shut" , "It's nearly open" .)
