Left American band on road, in the red (7)
I believe the answer is:
retired
'left american' is the definition.
'retired' can be an answer for 'left' (I've seen this before). I'm not certain of the 'american' bit.
'band on road in the red' is the wordplay.
'band' becomes 'tie' (a strip or band of material).
'on' indicates putting letters inside (as in clothing 'on' a person).
'road' becomes 'r' (this could be a standard abbreviation of which I'm unaware).
'in' is an insertion indicator.
'tie' enclosing 'r' is 'tire'.
'tire' put inside 'red' is 'RETIRED'.
Can you help me to learn more?
(Other definitions for retired that I've seen before include "Ceased working" , "In bed, withdrew" , "Gave up job, relaxed on pension" , "Stopped work - went to bed" , "claiming a pension?" .)
