I believe the answer is:
entirely
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">wholly and completely</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for entirely that I've seen before include "Without reservation" , "Altogether" , "Wholly, totally" , "Wholly, completly" , "without qualification _" .)
