Danced encircling northern banker in a flustered state (12)
I believe the answer is:
disconcerted
'danced encircling' is the definition.
I can't judge whether this defines the answer.
'northern banker in a flustered state' is the wordplay.
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'banker' becomes 'cert' (I've seen this before).
'in' means one lot of letters goes inside another.
'a flustered state' becomes 'discoed' (I can't explain this - if you can you should believe this answer much more).
'n'+'cert'='ncert'
'ncert' put inside 'discoed' is 'DISCONCERTED'.
Can you help me to learn more?
(Other definitions for disconcerted that I've seen before include "All shook up"" , "Unsettled" , "Disturbed the composure of" , "Second credit (anag) - thrown" .)
