Like American uncle somewhere in India (5)
I believe the answer is:
assam
'in india' is the definition.
('Assam' is part of 'india')
'like american uncle' is the wordplay.
'like' becomes 'as'.
'american uncle' becomes 'Sam' (Uncle Sam is a nickname for the USA).
'as'+'sam'='ASSAM'
'somewhere' is the link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for assam that I've seen before include "Type of tea" , "Leaves to get in hot water" , "Indian tea region" , "place associated with tea" , "Indian state famous for tea" .)
