Ancient Andes native (4)
I believe the answer is:
inca
'ancient andes native' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for inca that I've seen before include "Member of Andean people conquered by Spain" , "An old Peruvian like Cain" , "who lived in S America" , "S. Am native, lord in Quechua" , "Ancient Andean Indian" .)
