It goes to church, note (4)
I believe the answer is:
chit
'note' is the definition.
(I've seen this in another clue)
'it goes to church' is the wordplay.
'goes to' means one lot of letters go next to another.
'church' becomes 'ch' (common abbreviation).
'it' after 'ch' is 'CHIT'.
(Other definitions for chit that I've seen before include "Short official note recording a sum owed" , "Informal receipt" , "Pert young lady" , "A short written note" , "Official voucher" .)
