European bears in trouble (7)
I believe the answer is:
serbian
'european' is the definition.
(I've seen this before)
'bears in trouble' is the wordplay.
'trouble' is an anagram indicator.
'bears'+'in'='bearsin'
'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" .)
