I believe the answer is:
eve
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">day preceding</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for eve that I've seen before include "Night before an event" , "Adam & - -" , "Later in the day, in short" , "Girl" , "Day before (an event)" .)
