A service is brought up for tea (5)
I believe the answer is:
assam
'tea' is the definition.
(I've seen this before)
'a service is brought up' is the wordplay.
'service' becomes 'mass' (kind of church service).
'is brought up' says the letters should be written in reverse (in a down clue, letters go up).
'mass' reversed gives 'ssam'.
'a'+'ssam'='ASSAM'
'for' is the link.
(Other definitions for assam that I've seen before include "NE Indian state (tea)" , "Indian tea-growing area" , "brew?" , "Indian tea growing area" , "An Indian part" .)
