Worshipper of the sun god Inti (4)
I believe the answer is:
inca
'worshipper of the sun god inti' 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 "Member of ancient Peruvian tribe" , "South American (historical)" , "Andean culture" , "Member of old South American Indian people of Peru" , "Old person in race" .)
