Chapter has managed to indicate source of money (9)
I believe the answer is:
cashpoint
'source of money' 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 am not certain of the 'of money' bit.
'chapter has managed to indicate' is the wordplay.
'chapter' becomes 'c' (abbreviation).
'managed' indicates an anagram.
'to indicate' becomes 'point' ('point' can be a synonym of 'indicate').
'has' anagrammed gives 'ash'.
'c'+'ash'+'point'='CASHPOINT'
Can you help me to learn more?
(Other definitions for cashpoint that I've seen before include "ATM" , "Money dispenser" , "Somewhere one may obtain banknotes" , "source of funds" , "Automated teller machine" .)
