The German in the audience (3)
I believe the answer is:
die
'the german' is the definition.
('the' in German)
'in the audience' is the wordplay.
'in' says the answer is hidden in the clue.
'DIE' is hidden within 'audience'.
(Other definitions for die that I've seen before include "Cease living" , "Expire" , "Give out" , "Kick the bucket" , "Stop functioning" .)
