<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">tear to bits</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for shred that I've seen before include "Torn-off fragment" , "Strip of material; a very small amount" , "Cut into bits" , "Bit; cut or tear into tiny strips" , "Tatter; small amount" .)
