State within Afghan area (5)
I believe the answer is:
ghana
'state' is the definition.
(Ghana is an example)
'within afghan area' is the wordplay.
'within' indicates the answer is hidden within the clue.
'GHANA' can be found hidden inside 'afghan area'.
(Other definitions for ghana that I've seen before include "West African country, independent since 1957" , "Former Gold Coast" , "Ah, nag one into going to Africa" , "part of Africa" , "nation" .)
