City involved in business English? (5)
I believe the answer is:
essen
'city' is the definition.
(Essen is an example)
'involved in business english?' is the wordplay.
'involved in' says the answer is hidden in the clue.
'ESSEN' can be found hidden inside 'business english'.
(Other definitions for essen that I've seen before include "European city" , "German industrial centre" , "Main industrial city of the Ruhr" , "city in the Ruhr valley" , "German industrial city on the Ruhr" .)
