<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">truss</span>' is the definition.<br/ ><span class="explanation-format__explanation">(both can mean a tied up amount of something)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for bale that I've seen before include "Unit of hay" , "(Make into a) bundle of hay" , "Bound bundle" , "Bundle (of hay, say)" , "Bundle of hay or cotton" .)
