Apply again (5)
I believe the answer is:
reuse
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">apply again</span>' is the definition.<br/ ><span class="explanation-format__explanation">('use' can be a synonym for 'apply' so perhaps 'reuse' is OK for 'apply again')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for reuse that I've seen before include "Recycle (something)" , "For another time enjoy" , "The aim of recycling" , "Employ again" .)
