Not normal (8)
I believe the answer is:
aberrant
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not normal</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 aberrant that I've seen before include "Anomalous" , "Departing from accepted standard" , "Irregular" , "Departing from the norm" , "'Deviant, behaviour say (8)'" .)
