I believe the answer is:
inapt
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not appropriate</span>' is the definition.<br/ ><span class="explanation-format__explanation">(inapt means inappropriate or ill-fitting)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for inapt that I've seen before include "Unsuitable - paint (anag)" , "Improper" , "badly judged" , "Out of place" , "Free from deceit" .)
