Meant never to appear in the paper (7)
I believe the answer is:
denoted
'meant' is the definition.
(denoting is a kind of meaning)
'never to appear in the paper' is the wordplay.
'never' becomes 'not' (I've seen this in other clues).
'to appear in' is an insertion indicator.
'the paper' becomes 'deed' (I can't explain this - if you can you should give a lot more credence to this answer).
'not' put into 'deed' is 'DENOTED'.
Can you help me to learn more?
(Other definitions for denoted that I've seen before include "Signified" , "Indicated or meant" .)
