Feature in newspaper is great! (5)
I believe the answer is:
facet
'feature' is the definition.
(facet is a kind of feature)
'in newspaper is great' is the wordplay.
'in' means one lot of letters goes inside another.
'newspaper' becomes 'ft'.
'is great' becomes 'ace' (I've seen this before).
'ft' going around 'ace' is 'FACET'.
(Other definitions for facet that I've seen before include "Distinct feature" , "Angle" , "Aspect or feature of something" , "(Gem) side; aspect" , "Aspect - smooth cut surface" .)
