Perfumed items have to change (4)
I believe the answer is:
edit
'change' is the definition.
(edit can mean to change or alter)
'perfumed items have' is the wordplay.
'have' indicates a hidden word.
'EDIT' is hidden in the letters of 'perfumed items'.
'to' is the link.
(Other definitions for edit that I've seen before include "Censor" , "Alter text" , "Supervise the publication of" , "Rework (text)" , "Make changes to (text)" .)
