Only remaining (4)
I believe the answer is:
last
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">only remaining</span>' is the definition.<br/ ><span class="explanation-format__explanation">(the last thing is the only remaining thing)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for last that I've seen before include "Bringing up the rear" , "nowhere near winning Miss World?" , "Final; keep going" , "Cobbler's model shape" , "Form on which a shoe is made" .)
