Fix, as text (5)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">fix as text</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 emend that I've seen before include "Revise (a text) (E, not A)" , "Correct; edit" , "Edit, improve" , "Remove errors" , "make an improvement" .)
