Demands a lot of paper to support divinity lessons (8)
I believe the answer is:
requires
'demands' is the definition.
('require' can be a synonym of 'demand')
'a lot of paper to support divinity lessons' is the wordplay.
I cannot really see how this works, but
'paper' could be 'quires' (quantity of paper - 25 or 24 sheets) and 'quires' is found in the answer.
'divinity' could be 're' (Re is an example) and 're' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for requires that I've seen before include "Needs or demands" , "Has need of" , "Demands or wants" .)
