Accountant wrong about ring operating in gambling establishment (6)
I believe the answer is:
casino
'gambling establishment' is the definition.
(I've seen this before)
'accountant wrong about ring operating' is the wordplay.
I cannot quite understand how this works, but
'accountant' could be 'ca' (abbreviation for chartered accountant) and 'ca' is present in the answer.
'wrong' could be 'sin' (wrong can mean a sin or crime) and 'sin' is present in the answer.
'ring' could be 'o' (letter resembling a ring) and 'o' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for casino that I've seen before include "Where some gamblers go" , "Gaming-house" , "--- Royale (Fleming)" , "Gambling den" , "Building for gambling" .)
