Correct flow returns (4)

Ross

I believe the answer is:

edit

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

'flow returns' is the wordplay.
'flow' becomes 'tide' (tiding is a kind of flowing).
'returns' shows that the letters should be reversed in order.
'tide' backwards is 'EDIT'.

(Other definitions for edit that I've seen before include "Emend" , "Check text for publication" , "Manage a newspaper" , "Rewrite" , "Revise - expurgate" .)

I've seen this clue in The Guardian.
