<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">moxie</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 grit that I've seen before include "Small hard particles - determination" , "Gravelly courage" , "Pluck; sand particles" , "Determination - small stones" , "Coarse stone or sand" .)
