Not private (6)
I believe the answer is:
public
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not private</span>' is the definition.<br/ ><span class="explanation-format__explanation">('public' is the opposite to 'private')</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for public that I've seen before include "Accessible to all" , "Offence against common decency" , "Open to everyone" , "Open, known, generally" , "Serving the people" .)
