Aides, say, shouldn't carry papers (6)
I believe the answer is:
essays
'papers' is the definition.
(academic papers)
'aides say shouldn't carry' is the wordplay.
'carry' says the answer is hidden in the clue (I've seen 'carrying' mean this).
'ESSAYS' can be found hidden inside 'aides say shouldnt'.
(Other definitions for essays that I've seen before include "Literary efforts" , "Attempts, writing" , "Tries the writings" , "Tries for theses?" , "texts" .)
