<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">fight hand-to-hand</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 grapple that I've seen before include "Hooking instrument" , "Attempt to get hold of, or seize" , "Clutch" , "struggle" , "Fight hand-to-hand" .)
