One million papers cause admiration (7)
I believe the answer is:
impress
'admiration' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'one million papers' is the wordplay.
'one million' becomes 'im' (resembles 1m).
'papers' becomes 'press' (the newspaper industry).
'im'+'press'='IMPRESS'
'cause' acts as a link.
Can you help me to learn more?
(Other definitions for impress that I've seen before include "Inspire respect, stamp" , "Make a mark on, emphasise" , "Fix deeply in the mind" , "force to join navy?" , "Stamp, emboss" .)
