Eurasian mountain range (5)
I believe the answer is:
urals
'eurasian mountain range' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for urals that I've seen before include "mountain area" , "Mountains on the boundary between Europe and Asia" , "Russian mountains" , "Mountains of west-central Russia" , "Mountains of Western Russia" .)
