Religious teacher taking duck from zoo - a bird to put in the oven? (9)
I believe the answer is:
Here is my best explanation:
'religious teacher' is the definition.
'duck from zoo a bird to put in the oven?' is the subsidiary indication.
'duck' becomes 'o'.
'from' suggests deleting specific letters.
'a bird to put in the oven?' becomes 'roaster'.
'zoo' with 'o' taken out is 'zo'.
'taking' is the link.
