Piece of information (5)
I believe the answer is:
datum
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">piece of information</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 datum that I've seen before include "Fact or stat" , "Unit of dope" , "Given fact" , "One item of information" , "Bit of dope" .)
