I believe the answer is:
adrift
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not anchored</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for adrift that I've seen before include "like Mary Celeste?" , "Unanchored - lost" , "Disoriented" , "not settled" , "'Directionless, floating freely (6)'" .)
