Mountain range some can describe (5)
I believe the answer is:
andes
'mountain range' is the definition.
(Andes is an example)
'some can describe' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'ANDES' is hidden in the letters of 'can describe'.
(Other definitions for andes that I've seen before include "Mountains for the Danes, oddly" , "South American mountains" , "Major mountain range" , "South American mountain range" , "Mountains in west" .)
