Again go on about some state in America (6)

I believe the answer is:

oregon

I'm a little stuck... Click here to teach me more about this clue!

'state in america' is the definition.
(I know that Oregon is a U.S. state)

'again go on about' is the wordplay.
'again' becomes 're' (prefix meaning 'again').
'about' means one lot of letters goes inside another.
're'+'go'='rego'
'rego' inserted within 'on' is 'OREGON'.

'some' acts as a link.
This may not be right. It may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for oregon that I've seen before include "Part of the US" , "Salem's state" , "US west-coast state" , "US NW coastal state" , "Salem is this State's capital" .)
