Source of money in construction of china pots (9)
I believe the answer is:
cashpoint
'source of money in construction' is the definition.
'cashpoint' can be an answer for 'source' (I have seen 'source of funds' mean 'cashpoint' so perhaps 'source' could also mean 'cashpoint'). I'm unsure of the 'of money in construction' bit.
'of china pots' is the wordplay.
'of' indicates an anagram (the answer comes from or 'of' the letters).
'china'+'pots'='chinapots'
'chinapots' anagrammed gives 'CASHPOINT'.
Can you help me to learn more?
(Other definitions for cashpoint that I've seen before include "Automated teller machine" , "ATM" , "Where to get out money" , "source of funds" , "Somewhere one may obtain banknotes" .)
