City of Mali? (4)
I believe the answer is:
lima
'city' is the definition.
(Lima is an example)
'of mali?' is the wordplay.
'of' indicates an anagram (the answer comes from or 'of' the letters).
'mali' anagrammed gives 'LIMA'.
(Other definitions for lima that I've seen before include "Peruvian capital" , "Kind of bean" , "distant city" , "Edible bean; capital city" , "city (like 22)" .)
