<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not fit for consumption</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for inedible that I've seen before include "Not good as food" , "Unpalatable" , "Not fit for consumption" , "Unfit for consumption" , "needing to be taken off table?" .)
