Feature origin of African country (5)
I believe the answer is:
china
'country' is the definition.
(China is an example)
'feature origin of african' is the wordplay.
'feature' becomes 'chin' (chin is a kind of feature).
'origin of' says to take the initial letters.
The initial letter of 'african' is 'a'.
'chin'+'a'='CHINA'
(Other definitions for china that I've seen before include "Oriental country" , "Porcelain; friend" , "porcelain cups?" , "Asian country" , "Country - crockery" .)
