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' is an anagram indicator.
'around' means one lot of letters goes inside another.
'island' becomes 'i' (geographical abbreviation).
'bear'+'is'='bearis'
'bearis' with letters rearranged gives 'sibera'.
'sibera' placed around 'i' is 'SIBERIA'.
'in' is the 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)'" .)
