<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">testament</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for will that I've seen before include "Last testament" , "Written directions for disposal of estate after death" , "self-control" , "Intention, desire" , "Resolve - testament" .)
