European bears in trouble (7)
I believe the answer is:
'european' is the definition.
(I've seen this before)
'bears in trouble' is the wordplay.
'trouble' is an anagram indicator.
'bearsin' is an anagram of 'SERBIAN'.
(Other definitions for serbian that I've seen before include "European" , "Native of Belgrade perhaps" , "Foreigner" , "language!" , "Eg, Belgrade native" .)
