Annotate (4)
I believe the answer is:
mark
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">annotate</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 mark that I've seen before include "Gospel author" , "Scar; note" , "Indication - notice" , "Old money" , "[BOOK] of the 26 [BIBLE]" .)
