Selected passage (7)
I believe the answer is:
excerpt
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">selected passage</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for excerpt that I've seen before include "Selection, extract" , "A passage or quotation from" , "Piece from book etc" , "Piece selected from a film" , "Passage cut" .)
