Piece from tabloid staff in broadsheet (8)
I believe the answer is:
fragment
'piece' is the definition.
(I know that fragment is a type of piece)
'tabloid staff in broadsheet' is the wordplay.
'tabloid' becomes 'rag' (informal term for a tabloid newspaper).
'staff' becomes 'men' (I've seen this in other clues).
'in' indicates putting letters inside.
'broadsheet' becomes 'FT' (Financial Times, broadsheet newspaper).
'rag'+'men'='ragmen'
'ragmen' placed inside 'ft' is 'FRAGMENT'.
'from' is the link.
(Other definitions for fragment that I've seen before include "Scrap" , "Particle" , "Piece broken off something else" , "Bit" , "Incomplete part" .)
