Cup of tea taken in Bayreuth in Germany (5)
I believe the answer is:
thing
'cup of tea' is the definition.
(I've seen this before)
'taken in bayreuth in germany' is the wordplay.
'taken in' indicates a hidden word.
'THING' is hidden within 'bayreuth in germany'.
(Other definitions for thing that I've seen before include "Body" , "Individual object" , "Inanimate object" , "Affair - matter" , "Object, artefact" .)
