Range in Patagonian Desert, which it bounds (5)
I believe the answer is:
andes
'range in patagonian desert which it bounds' is the definition.
'andes' can be an answer for 'range' (South American mountain range). I'm not certain of the rest of the definition.
'range in patagonian desert' is the wordplay.
'range' says the answer is hidden in the clue (I've seen 'range of' mean this (a range of letters from the clue)).
'ANDES' can be found hidden inside 'in patagonian desert'.
Can you help me to learn more?
(Other definitions for andes that I've seen before include "Aconcagua the highest in this range" , "danes found in mountains" , "Mountains for the Danes, oddly" , "Danes seen in mountains" , "South American mountains" .)
