Man with articles for South American country (6)
I believe the answer is:
guyana
'for south american country' is the definition.
(country in South America)
'man with articles' is the wordplay.
'man' becomes 'guy' (guy is a kind of man).
'with' means one lot of letters go next to another.
'articles' becomes 'ana' ('an' and 'a', English indefinite articles).
'guy'+'ana'='GUYANA'
(Other definitions for guyana that I've seen before include "Country of S. America" , "Cricket-playing country" , "Country E. of Venezuela" , "South American country, a British colony until 1966" , "Off the north coast of S. America, the capital is Georgetown" .)
