Country exercise before game (4)
I believe the answer is:
peru
'country' is the definition.
(I know that Peru is South American country)
'exercise before game' is the wordplay.
'exercise' becomes 'pe' (Physical Education).
'before' is a charade indicator (letters next to each other).
'game' becomes 'ru' (rugby union).
'pe'+'ru'='PERU'
(Other definitions for peru that I've seen before include "Nazca, Cuzco here" , "South American republic" , "Paddington Bear's country of birth" , "Andes republic" , "Machu Picchu country" .)
