Books printed by agent provide new dirt? (5)
I believe the answer is:
'provide new dirt?' is the definition.
I can't judge whether this defines the answer.
'books printed by agent' is the wordplay.
I cannot really understand how this works, but
'books' could be 'ot' (abbreviation for Old Testament) and 'ot' is located in the answer.
'agent' could be 'rep' (short for representative) and 'rep' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for repot that I've seen before include "place somewhere new to put down roots" , "transfer seedlings" , "plant in another location" , "Transplant" , "Give room to expand" .)
