Dish dirt conclusively on teacher providing religious education for a bishop (7)
I believe the answer is:
rarebit
'dish' is the definition.
(rarebit is a kind of dish)
'dirt conclusively on teacher providing religious education for a bishop' is the wordplay.
I cannot quite see how this works, but
'on' could be 're' (regarding) and 're' is present in the answer.
'a' is found in the answer.
'bishop' could be 'b' (abbreviation for bishop in chess) and 'b' is found in the answer.
The remaining letters 'rit' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rarebit that I've seen before include "Savoury dish of cheese on toast" , "Cooked cheese on toast" , "on Welsh table?" , "Cheese on toast - arbiter (anag)" , "Cheese/toast savoury" .)
