Great section seen when Brazil and Argentina meet (5)
I believe the answer is:
large
'great' is the definition.
(I know that great can be written as large)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for large that I've seen before include "Big, great" , "Little's late partner" , "Stout" , "Strapping" , "Vast" .)
