Broody writers this writer's taken after (7)
I believe the answer is:
pensive
'broody' is the definition.
('pensive' can be a synonym of 'broody')
'writers this writer's taken after' is the wordplay.
'writers' becomes 'pens' (I've seen this before).
'this writer's' becomes 'ive' (belonging to me).
'taken after' is a charade indicator (letters next to each other).
'pens'+'ive'='PENSIVE'
(Other definitions for pensive that I've seen before include "Deeply thoughtful" , "Brooding" , "Introspective, maybe moody" , "Engaged in deep thought" , "musing" .)
