In and around a Peruvian? (4)
I believe the answer is:
inca
'peruvian?' is the definition.
(the Inca were a historical people of Peru)
'in and around a' is the wordplay.
'and' is a charade indicator (letters next to each other).
'around' becomes 'c' (abbreviation for 'circa').
'in'+'c'+'a'='INCA'
(Other definitions for inca that I've seen before include "lived in Peru" , "Member of old Peruvian Indian race" , "Ancient Peruvian Indian" , "Language" , "member of historic race" .)
