Barely enough hypocrisy after school (5)
I believe the answer is:
scant
'barely enough' is the definition.
(scant means barely enough or barely sufficient)
'hypocrisy after school' is the wordplay.
'hypocrisy' becomes 'cant' (I've seen this in another clue).
'after' is a charade indicator (letters next to each other).
'school' becomes 'S'.
'cant' put after 's' is 'SCANT'.
(Other definitions for scant that I've seen before include "Reduce" , "Meagre" , "Limited, inadequate" , "Less than the required amount" , "Bare" .)
