I believe the answer is:
nearest
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">most close</span>' is the definition.<br/ ><span class="explanation-format__explanation">('near' can be similar in meaning to 'close')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for nearest that I've seen before include "Closest, being earnest" , "touching?" , "In greatest propinquity" , "Most local" , "Most adjacent" .)
