Writer getting no new flag (6)
I believe the answer is:
pennon
'flag' is the definition.
(pennon is a kind of flag)
'writer getting no new' is the wordplay.
'writer' becomes 'pen' (something which writes).
'getting' is a charade indicator (letters next to each other).
'new' becomes 'n' (abbreviation as in New Testament NT).
'pen'+'no'+'n'='PENNON'
(Other definitions for pennon that I've seen before include "Knight's personal flag" , "Narrow, swallow-tailed standard" , "Long flag, often tapering" , "tapered flag" , "Ship's tapering flag" .)
