Cameron's returning to visit North American state (6)
I believe the answer is:
nevada
'state' is the definition.
(Nevada is an example)
'cameron's returning to visit north american' is the wordplay.
'cameron' becomes 'dave' (I can't explain this - if you can you should believe this answer much more).
'returning' is a reversal indicator.
'to visit' is an insertion indicator.
'north american' becomes 'na'.
'dave' reversed gives 'evad'.
'evad' placed within 'na' is 'NEVADA'.
Can you help me to learn more?
(Other definitions for nevada that I've seen before include "US state, capital Carson City" , "State including Las Vegas" , "US desert state" , "Curiously, Dan and Eva are in the US" , "Arid US state" .)
