Rise in current is correct (4)
I believe the answer is:
edit
'is correct' is the definition.
(thesaurus)
'rise in current' is the wordplay.
'rise in' shows that the letters should be reversed in order.
'current' becomes 'tide' (I've seen this before).
'tide' reversed gives 'EDIT'.
(Other definitions for edit that I've seen before include "This is an act of cleaning" , "Prep for press" , "Prepare (material) for publishing" , "Prepare (text) for issue" , "be a bookmaker" .)
