Check return of tide (4)
I believe the answer is:
edit
'check' is the definition.
(edit can mean to check or emend)
'return of tide' is the wordplay.
'return of' is a reversal indicator.
'tide' backwards is 'EDIT'.
(Other definitions for edit that I've seen before include "Supervise the publication of" , "Check text for publication" , "doctor" , "Be in charge of (newspaper)" , "Adjust text" .)
