Datum (4)

Ross

I believe the answer is:

fact

'datum' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for fact that I've seen before include "True item; reality" , "Undisputed truth" , "It's certainly not fiction" , "Actuality" , "Truth, reality" .)

I've seen this clue in the Newsday, The Mirror, the King Feature Syndicate, the Evening Standard and The Guardian.
