Church officer in Daniel Deronda (5)
I believe the answer is:
elder
'church officer' is the definition.
(elder is a kind of church officer)
'in daniel deronda' is the wordplay.
'in' indicates a hidden word.
'ELDER' is hidden within 'daniel deronda'.
(Other definitions for elder that I've seen before include "Older person - one's senior" , "sort of statesman" , "Patriarch" , "Shrub, tree" , "Shrub - church official" .)
