Escape clauses (4)
I believe the answer is:
outs
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">escape clauses</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for outs that I've seen before include "Forces to leave state of concealment, exposes" , "Publicly exposes a person's secret nature" , "Reveals" .)
