Vehicle in Central African Republic, originally (3)
I believe the answer is:
car
'vehicle' is the definition.
(I know that car is a type of land vehicle)
'central african republic originally' is the wordplay.
'originally' says to take the initial letters.
The initial letters of 'central african republic' is 'CAR'.
'in' is the link.
(Other definitions for car that I've seen before include "estate, perhaps" , "Private vehicle" , "4-wheeled vehicle" , "Hatchback, say?" , "Wheeled vehicle" .)
