Andorran general captures mountain chain (5)
I believe the answer is:
range
'mountain chain' is the definition.
(I know that mountain chain can be written as range)
'andorran general captures' is the wordplay.
'captures' indicates a hidden word (the answer is trapped within the clue).
'RANGE' is hidden within 'andorran general'.
(Other definitions for range that I've seen before include "Cooking stove or place for target practice" , "Selection" , "Ramble" , "Limits - scope" , "Prairie" .)
