Piece of bed linen (5)
I believe the answer is:
sheet
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">piece of bed linen</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 sheet that I've seen before include "Item of bed linen like these" , "Item of bedlinen" , "leaf" , "Piece of linen, paper, etc" , "* [MATERIAL]" .)
