Different concern getting book cancelled (5)
I believe the answer is:
other
'different' is the definition.
(similar in meaning)
'concern getting book cancelled' is the wordplay.
I cannot really see how this works, but
'book' could be 'ot' (Old Testament) and 'ot' is found in the answer.
The remaining letters 'her' 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 other that I've seen before include "Different, disparate" , "Alternate; additional" , "Not the one mentioned" , "Second" , "Throe (anag)" .)
