Confession (9)
I believe the answer is:
admission
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">confession</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 admission that I've seen before include "charge for entrance" , "Acknowledge of the truth of something" , "Anything conceded" , "A confessing" , "entry charge" .)
