Utopian article in Bild covering lots of paper (7)
I believe the answer is:
dreamer
'utopian' is the definition.
(thesaurus)
'article in bild covering lots of paper' is the wordplay.
'article in bild' becomes 'der' (definite article used in German newspaper Bild).
'covering' is an insertion indicator.
'lots of paper' becomes 'ream' (I've seen this before).
'der' going around 'ream' is 'DREAMER'.
(Other definitions for dreamer that I've seen before include "Gerontius" , "stargazer" , "Idealist - visionary" , "Fantasist" , "description of an Oxford spire?" .)
