Damaged book indeed (6)
I believe the answer is:
dented
'damaged' is the definition.
(similar in meaning)
'book indeed' is the wordplay.
I cannot quite see how this works, but
'book' could be 'nt' (New Testament) and 'nt' is found in the answer.
The remaining letters 'deed' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dented that I've seen before include "Tended to be depresed" , "Dinged" , "Made depression in through pressure or impact" , "Made small depression in metal surface" , "Bashed in" .)
