Heavy-handedly control work on newspapers (7)
I believe the answer is:
oppress
'heavy-handedly control' is the definition.
I can't judge whether this defines the answer.
'work on newspapers' is the wordplay.
'work' becomes 'op' (short for opus).
'on' says to put letters next to each other (in a down clue, letters appear on others).
'newspapers' becomes 'press' (the press is the newspaper industry).
'op'+'press'='OPPRESS'
Can you help me to learn more?
(Other definitions for oppress that I've seen before include "Treat harshly" , "Treat tyrannically" , "Govern cruelly" , "Crush, subjugate" , "'Persecute, come down heavy on (7)'" .)
