Gives up tea (6)
I believe the answer is:
leaves
I believe this clue is a double definition.
'gives up' is the first definition.
('leave' can be a synonym of 'give up')
'tea' is the second definition.
(tea leaves)
(Other definitions for leaves that I've seen before include "Departs with what fall in the Fall" , "Foliage - goes away" , "''... of Grass'' (Walt Whitman)" , "Departs with tree growths" , "Departs with book pages?" .)
