Dean confused about Virginia being a state (6)
I believe the answer is:
nevada
'a state' is the definition.
(Nevada is an example)
'dean confused about virginia' is the wordplay.
'confused' indicates an anagram.
'about' indicates putting letters inside.
'virginia' becomes 'va' (US state abbreviation).
'dean' with letters rearranged gives 'neda'.
'neda' enclosing 'va' is 'NEVADA'.
'being' acts as a link.
(Other definitions for nevada that I've seen before include "US state, NV" , "Southwestern US state" , "See 14" , "part of US" , "American state, capital Carson City" .)
