Chinese dynasty in East Anglia (4)
I believe the answer is:
tang
'chinese dynasty' is the definition.
(I've seen this before)
'in east anglia' is the wordplay.
'in' indicates a hidden word.
'TANG' can be found hidden inside 'east anglia'.
(Other definitions for tang that I've seen before include "Piquancy - Chinese dynasty" , "Bitter aftertaste - prong" , "Strong flavour/smell" , "The biting flavour of seaweed" , "Dynasty's" .)
