Insecure (6)
I believe the answer is:
unsafe
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">insecure</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that insecure can be written as unsafe)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for unsafe that I've seen before include "Dangerous - legally without basis" , "Perilous" , "Unreliable" , "Hazardous" , "Risky - inadequately evidenced" .)
