Andean Indian (4)
I believe the answer is:
'andean indian' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for inca that I've seen before include "Old person in race" , "Native Peruvian" , "Member of ancient Peruvian tribe" , "Early Peruvian" , "Pre-conquest Andean" .)
