Push for editing the magazine piece (5,7)
I believe the answer is:
press cutting
'magazine piece' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'push for editing' is the wordplay.
'push' becomes 'press' (press can mean to force or push).
'for' says to put letters next to each other.
'editing' becomes 'cutting' ('cut' can be a synonym of 'edit').
'press'+'cutting'='PRESS-CUTTING'
'the' is the link.
Can you help me to learn more?
(Other definitions for press cutting that I've seen before include "newspaper article" , "Item snipped from newspaper" .)
