Letter for letter (9)
I believe the answer is:
literatim
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">letter for letter</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 literatim that I've seen before include "one letter at a time" , "showing no change of character" .)
