African gin peaty when mixed (8)
I believe the answer is:
egyptian
'african' is the definition.
(I know that Egyptian is a type of african)
'gin peaty when mixed' is the wordplay.
'when mixed' indicates anagramming the letters.
'gin'+'peaty'='ginpeaty'
'ginpeaty' with letters rearranged gives 'EGYPTIAN'.
(Other definitions for egyptian that I've seen before include "New African democrat" , "Like a type of goose" , "tongue, once" , "ancient language" , "Nationality of Cleopatra" .)
