Church official appears in Daniel Deronda (5)
I believe the answer is:
elder
'church official' is the definition.
(as in church elders)
'in daniel deronda' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ELDER' can be found hidden inside 'daniel deronda'.
'appears' acts as a link.
(Other definitions for elder that I've seen before include "Senior tribal figure" , "Senior leader" , "Church official; tree" , "senior church member" , "Bush" .)
