I restate revised dissertation (8)

Ross

I believe the answer is:

treatise

'dissertation' is the definition.
(I've seen this before)

'i restate revised' is the wordplay.
'revised' is an anagram indicator.
'i'+'restate'='irestate'
'irestate' with letters rearranged gives 'TREATISE'.

(Other definitions for treatise that I've seen before include "formal document" , "Learned work on particular subject" , "Long, detailed essay" , "Disquisition" , "Written composition" .)

I've seen this clue in The Globe and Mail.
