Country in which one is surrounded by wandering bears (6)
I believe the answer is:
serbia
'country' is the definition.
(I know that Serbia is a country)
'one is surrounded by wandering bears' is the wordplay.
'one' becomes 'i' (Roman numeral).
'is surrounded by' indicates putting letters inside.
'wandering' is an anagram indicator.
'bears' is an anagram of 'serba'.
'i' going inside 'serba' is 'SERBIA'.
'in which' is the link.
(Other definitions for serbia that I've seen before include "Rabies in former Yugoslavia" , "Braise (anag) - country" , "South-east European country" , "part of Europe" , "Belgrade's country" .)
