Reading through "America (Latin)" (7)
I believe the answer is:
perusal
'reading' is the definition.
(perusal is a kind of reading)
'through america latin' is the wordplay.
'through' becomes 'per' ('per' can mean through or by means of).
'america' becomes 'usa' (synonyms).
'latin' becomes 'l'.
'per'+'usa'+'l'='PERUSAL'
(Other definitions for perusal that I've seen before include "Scanning, reading" , "Thorough reading" , "A casual read or study" , "Examination, survey" , "Careful reading" .)
