Understanding about getting underwear in a state (8)

I believe the answer is:
nebraska
'a state' is the definition.
(Nebraska is an example)
'understanding about getting underwear in' is the wordplay.
'understanding' becomes 'ken' (ken can mean someone's range of knowledge).
'about' says the letters should be written in reverse.
'getting' becomes 'a' (I can't explain this - if you can you should believe this answer much more).
'underwear' becomes 'bras'.
'in' means one lot of letters goes inside another.
'ken' reversed gives 'nek'.
'nek'+'a'='neka'
'neka' going around 'bras' is 'NEBRASKA'.
Can you help me to learn more?
(Other definitions for nebraska that I've seen before include "State N. of Kansas" , "Where Lincoln found" , "Midwest state - Springsteen album" , "State of central USA" , "US Great Plains state" .)
