Where China is attached to North East? (5)
I believe the answer is:
nepal
'where' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'china is attached to north east?' is the wordplay.
'china' becomes 'pal' (china plate is Cockney rhyming slang for mate).
'is attached to' is a charade indicator (letters next to each other).
'north east?' becomes 'ne'.
'pal' after 'ne' is 'NEPAL'.
Can you help me to learn more?
(Other definitions for nepal that I've seen before include "place in the mountains ..." , "Gurkhas' homeland" , "land" , "mountainous area" , "Asian kingdom" .)
