Paid excessively when too tired (9)
I believe the answer is:
overspent
'too tired' is the definition.
The answer and definition can be both to do with ownership as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'paid excessively' is the wordplay.
I cannot really understand how this works, but
'paid' could be 'spent' (spending is a kind of paying) and 'spent' is found within the answer.
'excessively' could be 'over' and 'over' is found within the answer.
No letters remain.
This explanation may well be incorrect...
'when' is the link.
Can you help me to learn more?
(Other definitions for overspent that I've seen before include "Beyond budget" , "broke" , "financial crisis" , "Used too much money" , "Bought too much" .)
