Rise in circulation of a paper (6)
I believe the answer is:
appear
'rise' is the definition.
(thesaurus)
'circulation of a paper' is the wordplay.
'circulation of' is an anagram indicator (letters circulated around).
'a'+'paper'='apaper'
'apaper' with letters rearranged gives 'APPEAR'.
'in' is the link.
(Other definitions for appear that I've seen before include "be published" , "Come into sight, materialise" , "Seem - come into view" , "Seem, look" , "Seem or materialise" .)
