Writer goes to church for money (5)
I believe the answer is:
pence
'for money' is the definition.
(I've seen this before)
'writer goes to church' is the wordplay.
'writer' becomes 'pen' (something which writes).
'goes to' says to put letters next to each other.
'church' becomes 'CE' (Church of England).
'pen'+'ce'='PENCE'
(Other definitions for pence that I've seen before include "offering to St Peter" , "Small coins" , "little money" , "''Take care of the ..... and the pounds will take care of themselves''" , "p" .)
