Mountains between Europe and Asia (5)
I believe the answer is:
urals
'mountains between europe and asia' 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 "Russian mountain range" , "Mountains of west-central Russia" , "Mountain range in Russia and Kazakhstan" , "Mountains on the boundary between Europe and Asia" , "Mountains of Western Russia" .)
