Rustic part of the lower Urals (5)
I believe the answer is:
rural
'rustic' is the definition.
(similar in meaning)
'part of the lower urals' is the wordplay.
'part of' indicates a hidden word.
'RURAL' is hidden within 'lower urals'.
(Other definitions for rural that I've seen before include "Characteristic of country life" , "Characteristic of the countryside" , "Cobbett saw on his rides?" , "Arcadian" , "Countryfied" .)
