The editor has to listen (4)
I believe the answer is:
heed
'to listen' is the definition.
(I've seen this in another clue)
'the editor has' is the wordplay.
'has' says the answer is hidden in the clue.
'HEED' is hidden in the letters of 'the editor'.
(Other definitions for heed that I've seen before include "Attend to, mind" , "Observe" , "Consider" , "Regard" , "Listen to carefully" .)
