Newspaper pieces featuring in newspaper piece (8)
I believe the answer is:
fragment
'piece' is the definition.
(I know that fragment is a type of piece)
'newspaper pieces featuring in newspaper' is the wordplay.
'newspaper' becomes 'rag' (informal term for a newspaper).
'pieces' becomes 'men' (man can mean a chess piece).
'featuring in' is an insertion indicator.
'newspaper' becomes 'FT' (Financial Times newspaper).
'rag'+'men'='ragmen'
'ragmen' put inside 'ft' is 'FRAGMENT'.
(Other definitions for fragment that I've seen before include "Piece broken off something else" , "Small portion" , "Come to pieces" , "Particle" , "Bit" .)
