European newspaper cuttings editor's hidden (8)
I believe the answer is:
eclipsed
'hidden' is the definition.
(I've seen this before)
'european newspaper cuttings editor's' is the wordplay.
'european newspaper' becomes 'e' (I am not sure about this - if you are sure you should believe this answer much more).
'cuttings' becomes 'clips' (clip is a kind of cutting).
'editor' becomes 'ed' (abbreviation).
'e'+'clips'+'ed'='ECLIPSED'
Can you help me to learn more?
(Other definitions for eclipsed that I've seen before include "Obscured as by heavenly body" , "Overshadowed" , "Hidden" , "Surpassed - led epics (anag)" , "Deprived of prominence" .)
