Urged by a journalistic editor (7)
I believe the answer is:
pressed
'urged' is the definition.
('press' can be a synonym of 'urge')
'a journalistic editor' is the wordplay.
I cannot really understand how this works, but
'editor' could be 'ed' (abbreviation) and 'ed' is found in the answer.
The remaining letters 'press' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'by' is the link.
Can you help me to learn more?
(Other definitions for pressed that I've seen before include "Argued strongly and exerted force" , "Urged U crushed" , "in a big hurry" , "Ironed" , "Forced" .)
