Not temporary (9)
I believe the answer is:
permanent
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not temporary</span>' is the definition.<br/ ><span class="explanation-format__explanation">('permanent' is the opposite to 'temporary')</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for permanent that I've seen before include "Lasting, enduring" , "that's not changing" , "Lasting, durable" , "Meant to remain indefinitely" , "Lasting indefinitely" .)
