Fool following university module (4)
I believe the answer is:
unit
'module' is the definition.
(thesaurus)
'fool following university' is the wordplay.
'fool' becomes 'nit' (I've seen this before).
'following' is a charade indicator (letters next to each other).
'university' becomes 'u'.
'nit' put after 'u' is 'UNIT'.
(Other definitions for unit that I've seen before include "Self-contained part" , "Piece of furniture" , "Kitchen fitting" , "Mexican maize pancake" , "Single item; one" .)
