Countryside in Outer Urals (5)
I believe the answer is:
rural
'countryside' is the definition.
(I've seen this before)
'in outer urals' is the wordplay.
'in' indicates the answer is hidden within the clue.
'RURAL' is hidden in the letters of 'outer urals'.
(Other definitions for rural that I've seen before include "Relating to the countryside" , "Bucolic; pastoral" , "Relating to country life" , "Pastoral or agricultural" , "Countrified" .)
