Where the Amazon rises (4)
I believe the answer is:
peru
'where the amazon rises' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for peru that I've seen before include "S American country, capital Lima" , "Country of Lima, Cuzco and Paddington Bear" , "Paddington Bear's country of birth" , "Lima's country" , "Machu Picchu country" .)
