Writer goes to church for money (5)
I believe the answer is:
pence
'money' is the definition.
(I've seen this before)
'writer goes to church' is the wordplay.
'writer' becomes 'pen' (something which writes).
'goes to' is a charade indicator (letters next to each other).
'church' becomes 'ce' (Church of England).
'pen'+'ce'='PENCE'
'for' is the link.
(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" .)
