Getting on with church, then one pint (7)
I believe the answer is:
receipt
'getting' is the definition.
(receipt is a kind of getting)
'on with church then one pint' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'with' means one lot of letters go next to another.
'church then' becomes 'ce' (Church of England. I am not sure about the 'then' bit.).
'one' becomes 'i' (Roman numeral).
'pint' becomes 'pt' (abbreviation).
're'+'ce'+'i'+'pt'='RECEIPT'
Can you help me to learn more?
(Other definitions for receipt that I've seen before include "old cook's directions" , "Sales slip" , "Proof of payment made" , "Confirmation of purchase" , "Written or printed acknowledgement or payment" .)
