Where, in the U.S., Ron's upset about his psychic self (6)
I believe the answer is:
oregon
'where in the u s ron's upset about his psychic' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'self' is the wordplay.
I cannot quite understand how this works, but
'self' could be 'ego' (synonyms) and 'ego' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for oregon that I've seen before include "US west-coast state" , "American state, capital Salem (6)." , "No gore seen in this American state" , "US north-western coastal state" , "America's Beaver State" .)
