Tangier confused North American: it's in South America (9)
I believe the answer is:
argentina
'in south america' is the definition.
('Argentina' is part of 'south america')
'tangier confused north american' is the wordplay.
'confused' is an anagram indicator.
'north american' becomes 'na'.
'tangier' with letters rearranged gives 'argenti'.
'argenti'+'na'='ARGENTINA'
'it's' acts as a link.
(Other definitions for argentina that I've seen before include "Evita's country" , "part of 18 [SOUTH AMERICA]" , "state" , "Silver country" , "Evita's land" .)
