Expert editor returning to newspaper (4)
I believe the answer is:
deft
'expert' is the definition.
(I've seen this in another clue)
'editor returning to newspaper' is the wordplay.
'editor' becomes 'ed' (abbreviation).
'returning' says the letters should be written backwards.
'to newspaper' becomes 'FT' (Financial Times newspaper).
'ed' backwards is 'de'.
'de'+'ft'='DEFT'
(Other definitions for deft that I've seen before include "Adept" , "Skilful, handling things easily" , "Handling things skilfully or neatly" , "Adroit, skilful" , "'Skilful, quick and neat (4)'" .)
