Bear is wandering around island in northern Russia (7)
I believe the answer is:
siberia
'northern russia' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'bear is wandering around island' is the wordplay.
'wandering' indicates anagramming the letters.
'around' means one lot of letters goes inside another.
'island' becomes 'i' (geographical abbreviation).
'bear'+'is'='bearis'
'bearis' with letters rearranged gives 'sberia'.
'sberia' placed around 'i' is 'SIBERIA'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for siberia that I've seen before include "region abroad" , "Eastern region of Russia" , "Region of Russia, from the Urals to the Pacific, famously cold in winter" , "Arctic region" , "'Region of Russia, famous for its long, cold winters (7)'" .)
