Office correspondence (4)
I believe the answer is:
memo
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">office correspondence</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 memo that I've seen before include "Short note or message" , "Reminder (abbr)" , "It will remind" , "Note written as a reminder" , "In brief, a note of events" .)
