A banker's flustered state in North America (8)
I believe the answer is:
nebraska
'state in north america' is the definition.
'Nebraska' can be an answer for 'state' (Nebraska is an example). I'm not sure about the 'in north america' bit.
'a banker's flustered' is the wordplay.
'flustered' is an anagram indicator.
'a'+'bankers'='abankers'
'abankers' with letters rearranged gives 'NEBRASKA'.
Can you help me to learn more?
(Other definitions for nebraska that I've seen before include "location of Lincoln" , "US Midwest state" , "American state, capital Lincoln" , "State of central US" , "US Great Plains state" .)
