Again catalogues begrudgers rejecting society (2-6)
I believe the answer is:
re-enters
'again catalogues' is the definition.
'begrudgers rejecting society' is the wordplay.
'begrudgers' becomes 'resenters' (people who begrudge others).
'rejecting' indicates named letters should be taken away.
'society' becomes 's' (common abbreviation in names of organisations).
'resenters' with 's' taken out is 'RE-ENTERS'.
(Other definitions for re-enters that I've seen before include "Goes in again" , "Comes back in" .)
