<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sloping script</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for italic that I've seen before include "Kind of typeface" , "Sloping type of print" , "Latin is" , "Relating to slanting handwriting or type" , "Print style used for emphasis, titles of books, etc" .)
