Charge a society girl for the thing in question (5)
I believe the answer is:
debit
'charge' is the definition.
(debit is a kind of charge)
'a society girl for the thing in question' is the wordplay.
'a society girl' becomes 'deb' (I've seen this in another clue).
'for' means one lot of letters go next to another.
'the thing in question' becomes 'it' (I am not sure about this - if you are sure you should believe this answer much more).
'deb'+'it'='DEBIT'
Can you help me to learn more?
(Other definitions for debit that I've seen before include "left-side entry" , "Enter in accounts as sum owed" , "Payment made or owed" , "Accounting entry showing sum owing" , "Accounting entry showing amount spent" .)
