Study South American country girl (7)
I believe the answer is:
perusal
'study' is the definition.
(thesaurus)
'south american country girl' is the wordplay.
'south american country' becomes 'peru' (Peru is an example).
'girl' becomes 'sal' (feminine given name).
'peru'+'sal'='PERUSAL'
(Other definitions for perusal that I've seen before include "Careful reading" , "Careful examination" , "Inspection" , "Thorough reading" , "A casual read or study" .)
