Ace new paper to be published (6)
I believe the answer is:
appear
'be published' is the definition.
(I've seen this in another clue)
'ace new paper' is the wordplay.
'ace' becomes 'a' (abbreviation).
'new' indicates an anagram.
'paper' with letters rearranged gives 'ppear'.
'a'+'ppear'='APPEAR'
'to' is the link.
(Other definitions for appear that I've seen before include "Perform" , "Seem or materialise" , "Show up, become visible" , "hove in sight" , "Seem, look" .)
