Tide's turning? Correct (4)

I believe the answer is:

edit

'correct' is the definition.
(edit can mean to correct or emend)

'tide's turning?' is the wordplay.
'turning?' is a reversal indicator.
'tide' back-to-front is 'EDIT'.

(Other definitions for edit that I've seen before include "Prepare text for publication" , "Ready for publication" , "Rework (text)" , "Make textual changes" , "amend copy" .)

I've seen this clue in The Everyman puzzle in The Observer.
