Member of ancient culture in Central America (4)
I believe the answer is:
inca
'member of ancient culture' is the definition.
'inca' can be an answer for 'culture' (I have seen 'Andean culture' mean 'inca' so perhaps 'culture' could also mean 'inca'). I'm not certain of the 'member of ancient' bit.
'in central america' is the wordplay.
'central' becomes 'c' (common abbreviation in various government acronyms).
'america' becomes 'a' (common abbreviation - e.g. in organisation names).
'in'+'c'+'a'='INCA'
Can you help me to learn more?
(Other definitions for inca that I've seen before include "Member of old South American Indian people of Peru" , "Old person in race" , "Old Peruvian people" , "Early Peruvian" , "An old Peruvian like Cain" .)
