Part of India like South America? (5)
I believe the answer is:
assam
'part of india' is the definition.
('Assam' is part of 'india')
'like south america?' is the wordplay.
'like' becomes 'as'.
'south' becomes 's' (abbreviation).
'america?' becomes 'am'.
'as'+'s'+'am'='ASSAM'
(Other definitions for assam that I've seen before include "Indian tea-producing region" , "Indian tea-growing state" , "Asian area?" , "An Indian part" , "I'll provide lots of tea" .)
