Put wrath in provocative writing (6)
I believe the answer is:
satire
'provocative writing' is the definition.
'put wrath' is the wordplay.
'put' becomes 'sat' (both can mean positioned or placed).
'wrath' becomes 'ire' ('ire' can be a synonym of 'wrath').
'sat'+'ire'='SATIRE'
'in' acts as a link.
(Other definitions for satire that I've seen before include "Writings ridiculing vice and folly" , "burlesque" , "Mocking humour" , "Lampoon(ery)" , "text of Juvenal" .)
