Revise bright idea withdrawing clothes (4)
I believe the answer is:
edit
'revise' is the definition.
(I've seen this in another clue)
'bright idea withdrawing clothes' is the wordplay.
'clothes' indicates a hidden word (the letters clothe the hidden word).
'withdrawing' shows that the letters should be reversed in order.
'tide' can be found hidden inside 'bright idea'.
'tide' written backwards gives 'EDIT'.
(Other definitions for edit that I've seen before include "Adjust text" , "Supervise - amend" , "be a bookmaker" , "Change text" , "Prepare text for press" .)
