Reword part of deed italicised (4)
I believe the answer is:
edit
'reword' is the definition.
(I've seen this in another clue)
'part of deed italicised' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'EDIT' can be found hidden inside 'deed italicised'.
(Other definitions for edit that I've seen before include "Be in charge of (newspaper)" , "Be in charge (of paper)" , "Revise text" , "Censor" , "work on newspaper?" .)
