Hang about a country in Africa (5)
I believe the answer is:
ghana
'country in africa' is the definition.
(African nation)
'hang about a' is the wordplay.
'about' is an anagram indicator.
'hang' is an anagram of 'ghan'.
'ghan'+'a'='GHANA'
(Other definitions for ghana that I've seen before include "Former Gold Coast" , "Language deriving from ancient Egyptian" , "Its capital is Accra" , "Woody raspberry stem" , "nation" .)
