Beginning to rake in loads of money in minor charges (5)
I believe the answer is:
wards
'minor charges' is the definition.
(I've seen this in another clue)
'beginning to rake in loads of money in' is the wordplay.
'beginning to' suggests taking the first letters.
'in' indicates putting letters inside.
'loads' becomes 'd'.
'of money' becomes 'was' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in' is an insertion indicator.
The first letter of 'rake' is 'r'.
'd' placed into 'was' is 'wads'.
'r' placed into 'wads' is 'WARDS'.
Can you help me to learn more?
(Other definitions for wards that I've seen before include "Hospital divisions" , "Charges" , "Hospital rooms" .)
