You'll have got ready to settle thus (3,2,4)
I believe the answer is:
pay in cash
'you'll have' is the definition.
The answer and definition can be both to do with ownership as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
'ready to settle thus' is the wordplay.
I cannot quite understand how this works, but
'ready' could be 'cash' (ready can informally mean cash) and 'cash' is located in the answer.
'settle' could be 'pay' (paying is a kind of settling) and 'pay' is located in the answer.
The remaining letters 'in' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'got' is the link.
Can you help me to learn more?
