Disturbed when in arrears? (9)
I believe the answer is:
unsettled
'disturbed' is the definition.
(I know that disturbed can be written as unsettled)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for unsettled that I've seen before include "Disturbed" , "lawless" , "Not sure" , "(Of weather) lacking stability" , "Missing work by composer, perhaps" .)
