I believe the answer is:
serif
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">letter embellishment</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 serif that I've seen before include "Detail on some typefaces" , "stroke of the pen" , "Part of letter" , "Slight projection finishing off printed letter - puts fires out" , "One feature of text" .)
