I believe the answer is:
except
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">excluding</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that excluding can be written as except)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for except that I've seen before include "Not including - bar" , "Exclude, take out" , "Other than - saving" , "Leave out, exclude" , "Rule out - unless" .)
